FI and I went to a baby shower LAST January (so 2010) and we NEVER received a thank you card.
FI and I then went to these people's wedding in September, and we NEVER received a thank you card.
I know it is silly, but for some reason this has really bothered me! I could never imagine doing that... blah.
I guess what made me think about this is FI's aunt sent us a thank you card last week for the Christmas gifts we gave her (she is speedy!), and it makes me angry that it's been a year and we still haven't gotten ONE thank you card for this girl who we attended both the baby shower and wedding. Grrr.
I will make sure I am not this person!
