A Hopscotch Puzzle

We saw some boys playing hopscotch, and wondered whether the figure marked on the ground could be drawn in one continuous stroke.

Can the reader draw it without taking the pencil off the paper or going over the same line twice?

Solution

It is necessary to start at $A$ and end at $B$, or start at $B$ and end at $A$, otherwise it can't be done.
