On the phone

Last week at the end of 3 different telephone conversations with men, he was told "I love you too" (1 x) and blown kisses (2x). Are we so in the habit that we don't even realize how we are ending a conversation? Maybe it's a little like when Stan and I started holding hands a lot and I would be walking next to a friend and try to hold their hands. Either way, 3 in a week is a bit strange.
