Tae for two

We do tae kwondo, my daughter, my grandson and me - well, all right, to be exact, my step-grandson. We all go together on Sunday evening. We're different grades.

• Grandson is white belt - for innocence and beginner.
• I'm blue tag, so my belt is green with a blue strip. It means the grade is half way between green and blue - for growing and getting there.
• Daughter is red tag, which is half way between blue and red - red means danger and she's getting quite scarily good.

We start with jogging and warm ups and then perhaps sparring in pairs. This Sunday for the first time, grandson and I got paired together. Imagine it! It's not often that Nanna and six-year old get to beat each other up.

Now grandson doesn't talk much - a bit like his grandfather but he can laugh. He didn't say a word as we hit with one fist, ducked and hit with the other fist, but he laughed fit to burst as he jumped to tag me on my head. And he laughed and laughed as we sparred. And when we had to take up press up position and try to knock each other off balance by pulling or knocking an arm, we both collapsed on the floor laughing.

That's why I do tae kwondo because it makes me laugh.
