I will pray for your son’s safety, but take heart.
I was a little younger than he when I decided it was time to go face the big bad world.
He may seem young for his age as you say, but that may be his love and respect for his mother giving you that impression.
It doesn’t matter where, or how old he is, he’ll always have those “I need to talk to Mom” moments. I still do. I’m 51, and my mom’s been passed since 1993.
It sounds like you raised him right. Have faith in those lessons, and understand that your son’s desire to prove his manhood, and independence, are a direct result of his upbringing, and the instinctual desire to pass it on to the next generation.
My crystal ball says, he’s just as likely to be successful, meet a beautiful girl, get married in a couple of years, and then we’ll get to congratulate you for those cute grandbabies!
God Bless you and him!
