SIL is getting married later this year, she has asked DD (6) to be a bridesmaid and DS (5) to be a pageboy, they have both said no. They don't want to dress up in clothes someone else has chosen and they don't want the extra attention/responsibility that comes with the job. This has been explained to SIL but she keeps insisting that they do it, she has sent wedding related presents to them along with a letter saying how much she'd like them to do it and has asked them several times. They still say no. She is pushing for me to insist that they do it, I think she should leave them alone and it shouldn't be mentioned again. AIBU?
In the spirit of full disclosure, I'm currently separating from H and SIL is not my favourite, although I don't actually dislike her, DC adore her.
