Father's Day: Gifts for dad not rocket science
The answer is less of a puzzle than Freud's query about what women want.
Dad wants to know that his kids love him. He wants to know that his time away from the family to put bread on the table was understood and that his time with the family is appreciated.
He wants to know that the kids still like his bedtime stories, tolerate his jokes, and understand that he really did walk for miles, uphill both ways, to school.
