I (26M) have a high-end laptop that I use for work and gaming. A friend of mine (28F) asked if she could borrow it for a week because hers broke and she needs it for a big project. I said no because I need it every day, and I do not feel comfortable lending out expensive electronics. She got upset and said I am being selfish since I could just use my phone for a while Now some of our mutual friends are saying I should have helped her out and that I value my stuff more than friendship. AITA for saying no, or was I right to set a boundary?
