I'm upset that I'm being excluded from parties as a mature student
Why does that make you upset?
I like parties and I would like to be friends with everybody
It's reasonable to be mad over being excluded by classmates. However, you must understand that people typically want to hang out with others their age.
Totally. I'm going to post this on the party page and start a big deal out of it.
You should not make this a big deal, you should just accept that they want to hang out with people their age.
