So, everyone has heard of a 25 year old guy marring a 19 year old girl, and thought nothing.
Or a 24 year old guy marrying a 26 year old girl.
At what point do you start wondering if everything is ok?
How about 28 year old guy and 19 year old girl?
How about 20 year old guy and 25 year old girl?
What are your cutoffs before you start snickering to yourself (and maybe to your chavrusah, just a bit)
