Maybe this conversation will give you a clue:
Gabi: Momma, why do you have glasses?
Momma: Because they help me see better, sweetie.
Gabi: So do you always NEED your glasses?
Momma: (starts to murmur mmmhmmm, then starts having a sneaking suspicion that the three-year-old is about to try to take her glasses) Well, they really help me see better but I could take them off if I wanted. (translation: Lies! I can't see a foot without my glasses!)
Gabi: OH. Well, you can keep them then I guess. (thank you so much!)
Gabi: Momma, did you have glasses before?
Momma: Before what? Oh, do you mean when I was a little girl?
Gabi: No, I meant when you were a boy.
(Don't be too shocked if you see our family on Dr. Phil one of these days!)
and just the other day she told me that my hair looked "rectangly." How sweet!
