ugh, yes. i was a "returning student" as well. I was old enough to be their mom. group work was painful. I'd try to hook up with at least one other older female, or someone who seems invested in working hard. enrolling in evening classes is best since you'll find the most oldies there.

you can't avoid this problem sadly. Here's a few techniques I used. I considered it a teaching opportunity. show them by example another way to act. when they put someone down, try asking, "i wonder why that person is like that - what do think their childhood was like?". help them develop empathy.

or try using humor, "wow - do you guys like ANYONE?" or, heck...just change the subject.

good luck!!
