They have a box of proper pavement chalks and want to do pictures on the pavement outside the house. I think that's fine as it'll wash off easily enough and the weather is predicting rain anyway tomorrow. I also don't think that anyone will have a problem with childrens drawings done in chalk on a public pavement.
My husband however, disagrees. He says it looks messy and is akin to graffiti. He doesn't think the neighbours will appreciate it at all and has banned them from doing so, instead they are limited to a patch of tarmac in the back yard.
So who is right here and who is wrong?
