I'm curious what your sense of nostalgia is like?

For me I think it's reasonable low. Like I look back at certain things, events and people of my past and I will think fondly of them. But I don't think about it often, and I almost never think "I miss that thing", more so that I enjoyed it at the time and I'm glad that it happened.

What about you? How do you view nostalgia? Does it bother you that things aren't the same as before? What things do you miss?
