Replying to Shitty house watchers

just got back from vacation. we hired two people to watch our house while we were gone. they are good people, i have known them for a while. however they fucked around with my x box 360 and broke it. also a couple years ago we hire a lady to watch our house. she decided to invite people over and they broke our trampoline. they managed to snap the bars on the trampoline. long story short everytime we leave we hire different house sitters and they manage to break exspensive shit
