When boys never bring girls to see relatives and friends, they always go by themselves when playing with friends, never bringing girlfriends or buddies.

No, I have a friend who is like this. He told him several times not to take him out with his date, not for fear that the date would be bad, but for fear that you would have too much contact with his brother. This is a man's vanity, afraid of too much, afraid of what you and his friends have.

Don't think too much, you will be very tired.
