Complain #1: If I don't call  her to let her know when I could be home, she thinks I do not respect her.... She will give me some COLORS.

Complain #2: If I call her when she is busy, she would give me more COLORS, right away... Why couldn't I find a better time to call, at least when she is less busy?  God, how could I know whether the kids would spend one hour eating the dinner, or 10 minutes, or whether they are taking shower or bath? 

Complain #3: Plus, if I call her and tell her when I would most likely to be home, she won't be happy neither.  Because, I could never do well estimating when I would be able to get home, working with R&D and international business conference calls just always take longer than I think they would. Than I would get COLORS ^2!

Complain #4: When I get home, I would not be able to take over and care for the kids. And she is all tired taking care of the kids.  COLORS ^ 4

Now, I don't call because I know she would give me COLORS just that once, and just for that one thing...  Taking one strong COLORS attack is easier than taking multiple over hours of span...
