So, a friend of mine borrowed my gaming PC for about a month because theirs broke. I agreed to lend it to them, but I was clear about the fact that I needed it back in a week. Now, a few weeks have passed, and they're acting like it’s no big deal, saying they'll “get around to returning it eventually." Meanwhile, I’ve been without my PC for way longer than expected and I kinda need it for work and personal stuff. I asked them to pay me back for the full price of the PC if they can’t return it soon, but they’re getting super defensive, saying I’m being selfish. AITA?
