How do I thank someone I don't even know??? UPDATE
I've only been dating this guy for a month (we have been talking for a total of 4 months). He went home for Christmas (home being Philly & we live in Ohio). He called me today on his way home & told me his mother got me a Christmas present! I haven't even met her yet! He tells me he talks about me all the time & she clearly thinks we are a good fit but she really didn't have to get me anything.
So now I need to know how I can thank her (haven't even opened the gift yet)? I was thinking a simple card & having him mail it to her for me. But other than that I have no idea how to thank her!
UPDATE: Thank you ladies for all the advice... I already knew I was going to send a thank you card... just wasn't sure if there was something else I should send. But now that I have the gift I thought you all might want to see? LOL I absolutely love it because it goes great in my living room (I have a red, white, & blue theme). I have it on a shelf with other precious things (things that I was allowed to take from my grandmother's home when she passed). This way my little stinker (4yo DS) can't get to it!
