Dad's mascot

At the beach, pressure's on
Dad in trunks and vest
Four years old, today's the day
He gives me my big test
Picking up a beach ball
Red, green, yellow, blue
He throws it at my feet
Wonders what I'll do
Do I kick it back?
Beautifully struck!
He's dying to get his son
Into a football strip
Or run away to build a castle
And precipitate the end
Of our relationship
