Okay, this is a weird question...?

So I received this email from some random guy asking me to get a next of kin doent because someone left me money in their will. I know, I too was like "Yea, okay, delete..." but the guy kept writing back showing me parts of the will, and it turns out I actually know this guy (kind of, he was at a play and we talked for awhile and he said if he had a daughter he would want her to be like me:) ) so... I don't know if I should believe this guy. What do you think? I mean if you were in my situation, if you received these emails and then it turns out you know this guy? This is kinda spooky... How can I tell if this is for real or not?
