I JUST want to ask the person who stole my seven-year-old son's new bike from the playground in Dulwich Park what right do you think you have?

We parked his bike with the other children's bikes in the bike rack and sat a few metres from them.

I deliberately didn't put it next to where we sat in case the little children running around tripped over it.

My son now thinks it is his fault and cannot comprehend why someone would take something belonging to him.

I try to bring my children up to respect other people's property - it's a pity more parents don't do the same with their children.

So whoever you are, I hope someone one day takes something of personal value to you.
