Has the guy complained about anything else? So odd that if he was so frustrated, why didn’t he just ask you how to best use it instead of complaining. I mean, for all things for a homeowner to have to worry about when away. Are you sure he knows which way to point the water when it comes out of the hose?
@Cat-ophile He did ask me at first and I gave him all the tips I could as well as copy-and-pasting a google query about it, but he still couldn’t operate it.
I’ve just had some photos from him, including one of my shed where he ‘suggested’ that I need to get shelves for it (something I know but haven’t managed to do so as yet). But in the shed were my shoes and wellies from my shoe rack inside - he’s reorganised that part of my home to suit himself which makes me wonder what else he’s reorganised, as if he’s moved in and not just housesitting. I’m livid!!! and told him what I think this time which he didn’t like at all, of course but I had to say something.
Reminds me of a distant relative I hadn’t seen in years. Said was in town and could they stay with me a few days. I had appointments on day one of their stay. I came home and they completely rearranged one on my rooms. Putting meaningful items I had displayed, now put away out of sight. Found items in closet and decided to rearrange my room. I was in shock. I had a cat and said to make sure you close front door behind you. My cat did go out in my large backyard but only with me. Never out the front door. I came home and the door was open as she said she went to get something from their car. My cat gone and was missing for 4 hours with me in hysterics that my heart cat was missing . I told that person to leave my home immediately. Other relatives said that person is a narcissist. Narcissist have no regard for others and they always think their way to do things is the right way and know better than you. I’m afraid your sitter may be one.
While he sounds supper annoying and thoughtless, be careful there. He is in your home after all. Thankfully no pets to displace his frustrations there. Consider asking him to leave if this is how things continue to go and you can’t hold your tongue. Nothing good will come of this for either side. Alternately dig deep and find a way to rise above his pettiness and get through the 3 weeks. Did he have a good review history (THS reviews, not merely references)? Did you happen to read the reviews he gave other Homeowners on past sits? There might be something you missed during the selection process for your sitter, taking time to dissect it all might prevent future frustrations. This one sounds insufferable!
Yikes! We have a word for this in my family. (starts with “jack; ends with “ss!)
I’d be tempted to offer to bring him a medal upon my return…he deserves nothing less than a purple heart for everything he’s suffering. 
@MTBer if it continues, I definitely will ask him tot leave. I know that his goal is to get a good review as this is his first sit with TH, my biggest mistake might’ve been wanting to give a new member a chance butt probably should’ve let him take on shorter sits for that. I really hope hope that my compassion doesn’t backfire so I won’t be doing that again. He had decent references but friends and family will do that won’t they?
When I spoke up, it was just to set boundaries and make it clear that reorganising my home wasn’t okay, nor did I appreciate being told what equipment I needed in my home.
He’s getting friendly with my neighbours so I know they’ll keep an eye out for me too, so far they really like him though. Fingers crossed.
If this was mentioned previously, I missed it. I cannot imagine how much more presumptuous he will be once he has some sits under his belt.
Oh wow you are kind 
. We all start somewhere.
This is a relief, at least you have someone nearby that you know/trust. He best turn around his crap attitude, bad assumptions and lack of filter if he wants to get a review that is not 1 
.
