I've been out all day and dh was looking after dd. This afternoon they were playing on the garden and he noticed a load of fag butts that had been chucked over the fence into our garden. Next door's elderly father smokes and logistically it can only be him. Husband was livid, scooped them all up then went round to confront. Nobody in so in a moment of madness posted them through the letter box. On ok terms with them. Few minor issues but nothing serious. I'm mortified and even though I agree pretty shit of the dad think dh overreacted. He is quite contrite. Would you go round to apologise?
