I feel your frustration.
This is what happened to my daughter. Her birthdfay was May 8. She called me all upset becauxe hubby had not even said Happy Birthday. So I called him at his work, and aked him if he had forgotten. He said NO. I said well your wife is upset because she thinks you did, but maybe you are planning a surprise. He says Yup I've got it covered.
This was the perfect time for him to cover his Butt. but NO
Mr Cluless, calls my daughter, and says "your mom just called, she thinks I forgot your birthdfay.". She says well you never said Happy Birthday,. He says well I thought you Knew???
He could have gotten home and said Where are the flowers I sent. I ordered flowers. Man now I'm PO'd, they better not have charged me for them. LOL
