Two sisters, about seven and nine, chase each other in a game of tag. Their three-year-old brother is desperately trying to gain their attention.
Boy: Guys! You got to include me, OK?
I smile, but my heart breaks. Being three is so hard. You're so big, but so little.
His sisters don't even notice him. They run off.
Boy: GUYS! You're s'posed to in-CLUDE me!
He runs crying to the car, where his mum waits. Minutes later, he is back. The tears are gone. His hands are on his hips. He has a secret weapon.
Boy: (confidently) Guys. Mum says you got to include me or we're going home.
