Things you never mastered in childhood

[SixteenFerreroRoches]

I can't go two skates and I can't whistle with my fingers. I'd LOVE to be able to whistle with my fingers.

I'd also like to be able to do a cartwheel.

I failed my cycling proficiency because, well I was not and still am not proficient at cycling. I can't let go of the handlebars to signal.

I can't ride a bike properly. I can't do a handstand unaided, I can't put my legs behind my head

Couldn’t throw or catch a ball, turn cartwheels, play cards, do decimals, knit, sing in tune.
