Well here is what I think :) One he is a guy. Bad excuse but he is a guy and most don't understand the time, effort and money that goes into something like that. Two if his fiancee doesn't know you and especially since they aren't married she may not feel that it is her responsibility to write a thank you. And third if they are of my generation (I'm in my 20's) they probably didn't even think to write one. In general we are very ungrateful with gifts. I am sure they love it but won't even consider writing a thank you. It really frustrates me as I am sure it does you. All my friends are at the prime age to be getting married and having babies. Yet I rarely get any sort of thank you. My mom always made me write them when I was little and I always do now as an adult but I rarely see them back in return. I guess my generation is just lazy. Or people are lazy in general. I have yet to see any thank you's from anyone in my DH's family. We've been married 4 years (together for 7) and have not seen one yet. Anyways now that I have ranted just don't take it too personally. I am sure they loved the quilt but they just may never get around to saying anything. Pretty much a shame :(
