Big news! On <date or day>, I'll be <way you'll be traveling> and coming out to see you! So you'd better tell all your other <boyfriends/girlfriends> to go home, because I'll be there soon.
Seriously, I can't wait to see you. <circumstances>. Wait until I tell you some of the things that have been going on around here!
Let me know if you want me to bring anything, or if you have some plans that I should take into account. Otherwise, I'll see you <date or day>. I can't wait to see you. I miss you terribly.
