This year is my grandparents 50 year anniversary. They got married when they were 16. My grandma tells me the story of how their parents took them to the courthouse then afterwards they went to the diner and had chocolate milk. Now that I'm planning my own wedding my grandma says how she wishes she could do something for her anniversary like a little wedding or whatever but she can't. I was thinking maybe at our wedding after FH and I have our first dance I could make an announcement how it's my grandparents 50th anniversary year and since they never got the chance to have a first dance I'd like them to have the floor. I haven't told her about it because I want it to be a surprise. Does this sound like a good idea or would our guests be wondering what the heck are we doing?
