SD, you can't judge a marriage by the public actions of a couple. My ex and I were very affection with each other. Always held hands, touched and tickled. We had the happy, happy family that all our friends envied. HA!! The man was wonderful til you got him behind closed doors. Put him in public and he couldn't keep his hands off me, put him in bed with me and he was very uninterested. Don't look at others and what you think they have because appearances are not always what they seem.
As for making the assumption that your daughter already had a mother's day card, well, you know what they say about the word assume? It makes an ass out of u and me! Never make assumptions about anything especially when it comes to something that can affect another person's feelings. Of course, the fact that your daughter is 16 and I'm sure knew that mother's day was upon her, she is responsible for making sure her mother gets a card. I'm not so sure I would take on all the responsibility for that mishap. Cathy~
