So I showed up late for a lab last week and had to partner up with this group of 4 girls. Now from the outside these girls were inseparable, the best of friends. Always talking and laughing with each other, I’d never see one without the other 3.

So anyway we’re working and one of the girls goes to the bathroom, and I kid you not-the MILLISECOND she stepped out of the door her 3 “friends” started talking shit about her. They talked about her hair, her outfit, her behaviour and were so rude I felt like stepping in but did nothing. Then of course when the girl came back they were friendly like nothing happened.
Are all girl friend groups shallow like this? It kind of made me sad for her ngl
