just ignore her.. no need to go and help... it is not your responsibility. Her daughter get marry, not your daughter. If she show you long face at her daughter's wedding day, you show her long face too...
Of course she doesn't care about your feeling, cos she doesn't have to work ( I assume) and doesn't need to take any young kids.
And don't ask your husband to go too.. cos he is a bus driver, expecially he need to work on early shift.. There are so many lifes on his hand each time. If he has lack of sleep and if causes any acciden, he will lose his job and will be in big trouble. mouth:
