Mother's Day has a very special place in the hearts of the majority of people in America. Hallmark estimates that 150 million Mother's Day cards will be sent this year (but only 95 million Father's Day cards), making Mother's Day the third largest greeting card holiday of the year. Americans spend an average of $105 on Mother's Day gifts, $90 on Father's Day gifts. The phone rings more often on Mother's Day than Father's Day, though Father's Day will have more collect calls. The busiest day of the year at car washes? The Saturday before Mother's Day.

What mom thinks still matters.
