I must really be a hopeless romantic. I never sent letters to famous people at all, because I couldn't even imagine it being possible until today. I live in another country, not in the US, even English not know so that immediately sorry me for my bad English. I'd like to ask. I can only send a picture of their character or a personal photo? So they can send an autograph?. Or I can write what the the text, a slight letter? If they can answer it or at least write a few lines or not, or do not send them a letter and photos only with their character? (if this the actor) I just don't want to do anything extra, I don't want them to be embarrassed or anything. I certainly do not want to write that I love them and want to get married and 5 children, no of course. Just something heartfelt. Not about love or threats.

Also I would like to ask, I from other country and if my letter does not reach the addressee? can send several at once? or should I never do that? xd
