Probably silly doubt

[absent-minded]

Hi, I just signed up just to check this out. I haven't seen any other channels have this type of question, sorry if I missed anything.

I've never written to any famous people (or paid much attention to their lives), but I saw you have the address of an actor I like and I want to write to him. It's his manager's address. How does this work? Do managers read letters? Do actors actually read their fans' letters? Any suggestions?

And another question, probably also a bit silly, but I've never really been interested enough in anyone to be a fan. What's the difference between an agent and a manager? He has both, and a publicist too...
