SIL, who has never concealed her contempt for DW, is attending the Christmas bash at our house under sufferance. MIL, BIL, and the charming nieces have jointly instructed her (her words) that she is to turn up cheerful, hold her tongue, and not drag everyone away early. Oh joy. My conscience tells me I should be a good host, the Devil is tempting me to tease her. Help me resist my black and twisted humour. /rant.
