hereditary bad habit

Pouring to much tea in the cup seems to be a hereditary bad habit: I did it when I was a kid, to my mothers frustration, and my children do it even though I tell them not to.

This picture actually is fake, staged by my daughter to show all children out there what happens if you first fill the cup to the brim with tea and milk, and then put a straw in it, and then add some water because you took too much milk in the first place. As she often does. So: don't try this at home, kids.
