My friend blew up my chests "for fun"

I introduced him to stardew and we've been having fun playing it for about 2 weeks. I've got over 1000 hours in the game so I was doing the combat stuff while he went fishing and romanced hailey. I told him I was off to the mines and I would pass out there exploring so he could skill until 2am.

I heard him say "oh s***" at one point so I said what happened? He said nothing nothing never mind. I heard him giggling to himself after that, I said what what? He said "you'll see" and kept giggling.

Well I passed out in the mines, it saved and passed to the next day. When I exited my house I saw all of my chests were gone, everything except his fish chest were gone. He was laughing hysterically saying that he had crafted some bombs and found out on accident he could blow up chests so he blew them all up.

Its not my main farm or anything but I was kinda pissed and didn't want to play after that. He wants to keep playing but I'm still feeling salty about it
