I've never been a fan of this question either, and I agree that it is often more trouble than it's worth, but it's interesting to hear what other people have to say. I figured it couldn't hurt since it is obviously voluntary to respond on here.
It's not like I'm in your face and pressuring you to come up with something. lol
I think personal experiences (like JaneQ's travel) ARE a part of what makes a person unique, so even if it isn't super personal it is still a great answer.
I also couldn't wink at all until about 6 months ago. For some reason I have very little control of my facial muscles and it was REALLY hard for me to learn. Years of trying, hard. To this day if I wink very often, my face will get all spazzy. Apparently it's really humorous to see, but I kind of hate not being able to wink with the ease that most people have.
