Caught red-handed

When I was very young,

I was bit of a...

 I was about five years old...

My dad was painting with white paint.

He was painting the garage door.

I kept dipping my finger in the paint,

Then adding a finger mark to the wall of the garage.

They found out where I had been putting those paint marks....

I was told off..

However after 39 years, they are still there...
