i'm so frustrated with the people in my school

So like my school was giving out free Eos lotion and lip balm today (tbh I’m not really sure why, but whatever, free stuff) and I heard so many boys say “I don’t want any, that’s girl stuff” or when a boy did take some someone else would say “Man why would you take that, it’s for girls” and I’m just…. Angry?? Like what does gender have to do with this?? Why are people like this it just frustrates me to no end??
