My dad is nervous about doing a solo father/daughter dance, but FI's mom has made it clear that she wants to do a mother/son dance. I would just skip the father/daughter dance and go right into the mother/son dance, but she is a big-time cryer. I think it will be awkward to have all the guests watching her sob on FI's shoulder for 3 minutes straight, but I don't want to tell her (or have FI tell her) that she can't have her moment with her son. My dad has agreed to dance with me as long as someone else is on the dance floor, so the compromise we have come up with is to have both couples dance at the same time. Any song suggestions that would be appropriate for all four of us, preferably something shorter or with a convenient place to fade out early?
