Most Helpful Guy
The fathers are concerned about their daughters, so they will want to evaluate the who will they marry. They had more experience in life than both of them and usually the man is older so this is normal (note that: if your husband is older than your father then...).
And from the Guy's view he wants to sell him self out and make a good impression as he have more chance to connect with your father (break the anxiety barrier) than you mother.
There is a similar (not the same) relation between the guy's mother and his woman.
