If your fiance dances with your mom, you should dance with his dad at the same time. Don't waste a bunch of time with a lot of solo dances. (your first dance, the son-mother dance, the father-daughter dance, after awhile, it gets old. speed it up, combine a few together, and let the guests loose on the dance floor).
If your fiance wants a dance with your mom then yes, you should. However, I think all the organized dances get kinda boring for the guests. So maybe it would be better if at some point during the reception your fiance just asked your mom to dance. If not, then I suggest you dance with his father at the same time that he dances with your mother.
It would be nice for you to dance with him while your fiance dances with your mom. If you don't really want to dance the entire song with him, just do a bit and then invite your fiance's mom to take over, so the two of them can dance together. That way, you are showing respect by dancing with the dad and also the mom by not leaving her out of the spotlight.
You dont have to if you dont want to...Why dont you just have the DJ play a slow song sometime during the reception and when it is played ur fiance can go ask ur mom to dance and you can dance with a friend or if his dad does ask you to dance just go with it....you dont have to initiate it...but if he does ask just be respectful and gowith it
Yes. It will take you two minutes or less. Think of it as a minor investment in family harmony that will yield a big return - no matter what he's like.
