Hey, so I recently got to interview this guy for the paper. We had a nice interview and it went smoothly. He was funny I laughed yata yata. But my question is, I went to add him on Facebook after being encouraged to do so by a mutual friend, and it didn't say friend request sent but it appeared I clicked the button. So now I'm stuck not knowing if he ignored it, or never got it. What do I do?

Send it again and this time leave a message to go with it, something like "Hi this is ............... and we met .................. and I'd like to be friends".
