Firstly because of lack of honesty when it comes to putting money in there. And secondly because either No 3 or No 4 son stole the contents!
I think they also may have stolen some of the contents of the purse in which I’ve been collecting donations from parents towards an end of term gift for our pre school. Either that or I borrowed some. But I don’t remember doing so. When I asked (very nicely and gently and calmly) whether anyone had taken money out of this particular purse, No 4 son admitted that he had. When asked to tell me where he had put it, he said in the middle of the living room floor. Having not seen any money in there I decided this may be a tall tale (he has equal fondness for stories and petty theft it would seem). This seemed especially likely when he said he put it there a year ago. Don’t worry any pre school mums reading this. I shall of course pay back whatever is missing. Doubt I’ll ever find out what happened to the missing money. It’s probably in the same place as the contents of the swear jar.
