For all those people who went back at a later age, I am curious what you experienced in terms of friendship or friendship attempts from fellow students.

It has me confused, for sure. For example, suddenly people I didn't expect to be friends go on holiday together. I wonder where these friendships start developing. And why those people, and not someone else.

And what is the attitude of those 20-someting year olds. Do they consider you as a potential friend? How? How not?
