Yay! Thats great! Look at you getting text messages off him right after you just met up with him! I'm very happy for you.
Hmm... well he did say specifically, where should I "send" it.. so maybe thats a subtle message that he wont have time to meet with you, but is being kind of caring by 'letting' you know and not just ignoring your text?
How about just giving him your address and wishing him lucj with whatever it is he is doing on Saturday?
