Today is my 20th anniversary.
I was a baby when I got married. Really. Only 21. I didn't know anything then except that DH was THE one. He still is.
I was still in university and DH often came down to visit and to get me out of dorm-room hell. We went to a jewelry store to get a silver tea set for his parent' anniversary (really for his mom -- I'm sure Pops didn't care about a tea set....). While we were waiting for it to be polished and wrapped we were leaning on the jewelry counter. Immediately beneath us were engagement rings. Good marketing, that.
I was looking at them, apparently DH was too because he said in the most romantic way possible "so, do you wanta do it?" I knew what he meant, said "sure, if you're serious." He was. We picked out a ring and lived happily (most of the time) ever after. The end.
