Is it normal for a guy to be very immature at 26?
I know a guy who is 26 and is still mentally like 14. He still acts exactly the same as he did in high school and is a complete jerk, and is even dating a girl who just graduated high school this year (they got together while she was still in high school).
Is it normal to be this immature and to have not changed at all from the time he was in high school to 26? Is there any hope he will ever grow out of it or will he be one of those guys who stays mentally at high school age forever?
