Memories of Romances Past

Let's talk about
1.) The one that got away;
2.) Your most attractive long time used to be;
3.) The one you were glad lasted one date (or, your biggest disappointment);
4.) The one who changed your language (I just used the phrase, "When I was a young sprout," which came from a former beau);
5.) The one who changed your life for the better;
6.) The one who changed your life for the worst.
