I mailed out the birthday card on Saturday. It should arrive today, or tomorrow at the latest. My hope is that I get a message saying thanks for the card or something of the sort. Assuming that I do get a message from her or some sort of contact, how should I respond? Just play it cool I assume? Say your welcome and I hope that you have a great birthday? I'm also assuming I shouldn't send a text saying happy birthday since I sent the card. Am I right in that? Thanks so much for the help!
