I shop for grocer ies at the campus supermarket. I find most students at my hostel are generally friendly enough to say hello, but that's mostly the level of conversa tion. Mostly, they have their own groups. I find that as I'm older, I can't keep up with high-energy levels of the younger students. I also need more time to sleep.
Noise is by far the major problem.
There's plenty of yelling and cheering. Then there are people who talk on the phone, past midnight, at the top of their voices outside my bedroom window. She brings a different perspective to the class, a perspective that people our age don't see. I've found that the older a student is, the less inhibited they are to speak up in class. Young people often worry about what others will think.
