My friend told on me and my boyfriend. What's his problem. and what's that lady's problem?

We were in the learning center kissing. ( the learning center is like a place for peer tutors to tutor other college kids) but everybody basically uses it as a lounge area.. And my guy friend is sitting there staring at us and he's like " you can't be doing all that PDA junk in here. it's not allowed". and i was like " um, mind ya buisness". We didnt even kiss that much we were mainly conversating. and it was kinda hot and stuffy up in there so he took off his shirt but he had a wife beater on underneath so he wasnt like shirtless. i see no problem at all. But the lady was like " if you're not doing homework you need to leave" and she like stood there until we left . gees we are not 12. this is insane
