The name has rarely been a problem for me, although some of my coworkers will get tongue tied when talking about old stories. Last time it was, "Remember that meeting in San Diego in 1987 when Bob, er... back when there was a Bob..."
Pronouns have always seemed more of a problem for old friends. Pronouns may stick longer than names.
Since I've been back in VA working full time (I'm supposed to be retired), I notice that even the guys I've worked with for well over 20 years, open doors for me. Remarkably, they still ask my advice and listen.
Eventually, it takes.
