I happened to call my Mom yesterday morning, around 10 am, and before I could even say "Hello" (she has caller ID so she always knows who is calling before she picks up the phone), she started in right away; complaining about how none of her three children had bothered to call her and wish her happy birthday...
I explained:
1. It was only 10 AM , the day was young
2. I was actually on the phone, at the very moment, having just called her
3. It was not her birthday
