R2C me too. Also I call or email next day and say I had a great time. If I call I make sure its when they are not home and its on the answering machine for when they get home from work. Usually along the lines of.
"Last night was really good. I had a great time. I hope your having a great day. And have a great week. I am having a really good day. Take care and talk to you later"
