Dear godshand:

You and a few friends then, have been in touch with a few university professors 10-12 years after graduating. Recently one of those few professors told you that it is not proper to be in touch with him/her.

Did you ask that professor why it is improper? And why now, after 10 years or more?

Did anything happen during that last meeting to suggest to you the reason?

You can also ask the other professors you are in touch with for their position on this, as they all taught or are teaching the same university.
