I'm socially retarded.

What do I say to someone who proudly tells me their grandson has the same name as me after they asked me what my name was?

How do I respond in a way that doesn't make them feel like shit for opening up to me for a brief second?

"It's a common name."

Compliment the name, it's a layup. Why are you defaulting to negativity/insults?

>fuck you asshole, you are a dumb faggot, don't overburden me with your personal shit I dont care
or
>oh that's nice, how old is he?

like other people, tell the man that it's a great name, and/or ask them about their grandson. People love to talk about their family, it's an easy way to get them to talk about themselves.
