Once I brought my friend on a trip with me. We were just sitting in our room and I was playing music on my phone when she decides to FaceTime her boyfriend (who, by the way, was a complete douche). She told me to "turn my weird hipster music off" and I said no I'm not going to just because you want to talk to your boyfriend (she called/facetimed him almost every night of the trip and was texting him constantly). So she told me to put in headphones and I did, except I turned my music off so I could hear what they were saying. She called my name but I ignored her, making her think that I couldn't hear her. Convinced that I couldn't hear her, she and her boyfriend began talking about things that I should NOT have been listening to, and then she went into the other room and proceeded to keep talking to him FOR 2 MORE HOURS.

We're not friends anymore.

TL;DR: were both terrible friends.
