Rochelle:
I think you are wrong to limit it to just a boy a year or two younger.
Just like it is no big deal to marry a girl 4 or 5 years younger, we need to get to the point where it is no big deal (and it isn’t!) to marry a boy 4 or 5 years younger than the girl.
EDIT: Rochelle, why did you delete the text of your post above??
