I'm rereading some old Pre-Crisis comics and it seems to me that Superman has more social life than Clark Kent. Perry White considers him a good friend, Lois Lane is more or less in love with him, and Jimmy Olsen is known as "Superman's Pal". On the other hand, Clark Kent is such a shapeless amoeba that it is not clear why someone would like to be friends with him. In fact, he always refuses friendship offers with some excuse as Superman's help is needed somewhere. So, whatever are his reason to keep a secret identity, keeping safe his loved ones is not one of them. Still, every time Lois Lane tries to talk about this subject, this is the justification he offers to her.
He was a dick.
