One day I bought my dad an unusual personal safe - a can of spray paint with a false bottom so he could keep his money in the workshop.
Later I asked my mum if he was using it.
"Oh, yes" she replied "he put his money in it the same day".
"No burglar would think to look on the work shelf!" I gloated.
"They won't have to" my mum replied.
