Age differences

I find it a bit odd how when you think of a 15 year old with a 18 year old it seems wrong but if they were 45 and 48 it seems perfectly normal. I understand that there is a difference in the development of the brain at the young ages but if you happen to find your sole mate in life at this young age, it seems wrong for people to judge just because of the age difference. Once we age the differences between the numbers seem to not matter. In fact the differences seem almost normal to the point that if you were the same age it seems odd to most. I find it a little odd myself when people are married that are the same age, yet I have no problem dating people my age, or older.

Thank you for reading!
