Some relationships like a 20-year-old girl getting married to a 60-70-year-old man are unacceptable for me as well because that girl has become old automatically and she will be feeling too old among her peers.

The same thing goes for a 20-30-year-old guy going into a relationship with a woman who is old enough to be his mother.

But then some relationships are never bad, if a lady is just two years older is still good
