Mother's Day is the busiest phone day of the year:
"We found that Mother's Day is far and away the most popular day to place phone calls across the world, registering more calling traffic than any other holiday, including New Year's and Valentine's Day."Father's Day has the highest number of collect calls of the year:
It gets better. Children often call dad to send their love but do so on his dime: Father's Day traditionally marks the year's busiest collect-call day for AT&T. And those who remember to send greeting cards do so in significantly smaller numbers.
For all you other fathers out there: enjoy your day. Have a barbecue. Do some shooting or fishing or something you like.
And pay for the call.
