Where's Dad

This morning through the keyhole I saw my  mommy crying, she was talking on the phone to grandma.
My dad didn't come home last night. Mommy said that she is worried about him and she was up all night. Mom and dad fuss at each other when he comes home late,  maybe he stayed at work so he wouldn't be late coming home, and he won't have to fuss about it. I hope he make it home soon, cause I hate to see mommy cry.
