I feel like I have always been shorter than Jan.
Are you worried about being short?
I always have a feeling of being left behind
Height is something that cannot be helped, it is due to genetics and we should make do with what we have. In order to be happy we have to accept the height we have.
What if I am tired of being the short one? There must be a good solution to this dilemma somehow.
I'm sorry you feel that way. It is good to be happy with whatever height you are. You can always wear heels to make you taller if you want.
