You can practically talk about anything and laugh or reminisce about it. At one level there are lot of things that changes in each one's life. On the other hand they looked the same to me. Same was with them . Most of them said " You just look the same" :-). If you forgot yourself or some of your best qualities, probably it is a good idea to meet some old friends.
There is a comfort that comes with familiarity. To be able to enjoy it probably some gaps are okay. I guess one values it more as one grows in life. This is one of the treasures I have been given that I truly cherish.
