I'll add from my own personal story, I did go off on my nieces boyfriend. My brother was one of those "try to be your child's friend" parents. My neice was 16. Her boyfriend was 18 or 19. My brother was concerned about the age, but thought he could manage it and not have her run to the guy if he didn't put his foot down.
One of those regulations was she was not to be riding in cars with him, so this lead to my brother having to pick her and her boyfriend up from the skating rink. He left his car at my brothers house. I was 26 at the time.
We pick them up and my brother and his wife are in the front. I'm in the back with the two of them. In the corner of my eye I see him give her a quick kiss. I felt uncomfortable but didn't want to overstep my boundaries as she wasn't my daughter. Then I hear him whispering. Terrified of what I'm about to see I look over at them. He's kissing her neck. Kissing her neck in a car full of her family.
Me: "What the fuck is wrong with you?"
Him: "What? I'm sorry. Chill out."
Me: "Chill the fuck out? You're just going to make out with her in front of her entire family? Are you fucking retarded?"
Him: "Calm down man s.."
Me: "Shut the fuck up"
Dead silence the entire ride. Uncomfortable as hell. When I was alone with my brother he said "don't you think you went a little overboard?" The only thing I could tell my brother was it would be even rude for one of my friends to be making out with his girlfriend next to me in a vehicle. It's a million times worse when it's a family member.
I have 3 boys. I wish I had a daughter, but the perfect kid would be a girl until 12-13 then a boy forever after. I don't like teenage girls and you'll always worry as a father about her as an adult. Little boy's crying to me though is like nails on a chalk board. Not that I think they should be tough, it's just that a crying young boy who is a brat is the absolute worst.
I've been blessed so far that my 2 1/2yr old son has empathy towards his little twin brothers. Has a very happy demeanor and "the terrible twos" have been the exact opposite. I think the age he's at is the most fun I've ever had with any child. He finds any excuse to dance and it's hilarious.
I've yelled at my son once his entire life. He was trying to shove things into an electrical outlet. He became terrified and I was seriously concerned. Then I was amazed because I thought "holy crap! His entire life he's never seen me angry. That was his first time seeing ANYONE angry".
