Confusion

Confusion has overcome me, as it does for most teenage girls.  The one of guys.  I am not even talking about guys that I like; just this guy that I am really good friends with.  I have known him for a pretty long time, and have never had this problem before, until now that is.  I was talking to him on the phone earlier and his boss called him, so I let him hang up on me and he said he was going to call me back when his conversation with his boss was over, well it's been well over an hour, and I still have had no reply.  Now, this wouldn't be such a big deal to me if I didn't have a super question to ask him, but I do, and he is not answering me.  I really don't think he is having an hour long conversation with his boss.  He never ignores me, though.  I don't really know what is going on.  Plenty of boyfriends have done that to me, or guys that knew that I liked them, or guys that have liked me have done that to me.  Not this guy though;  I don't have feelings for him and he doesn't have feelings for me (I'm pretty sure, I guess you never really know for sure).  I don't know why he would ignore me... and so, as I said before, confusion has overcome me.
