My FI is going to be dancing with my Grandmother at the wedding (she is the only grandparent left from both sides) anyway they are very close and are always teasing each other and stuff. ANyway I am having a hard time coming up with a song that fits. I have been finding songs that suggest things like over the years and stuff, but she hasnt known him for more than 3 yrs. So, I am turning to the professionals! I NEED HELP!
