IMO, you mistook small talk for conversation. There's a time for small talk and there's a time for conversation. It's kind of awkward when we as people get motivated enough to talk to other people, but can't read the signs when the small talk or the conversation have hit a stopping point.
Another opinion of mine I that you introduced yourself as more senior than them in your trade. Now it's up to them to want to continue the dialog. Just keep doing your thing your way, besides giving the new people a chance to choose to talk to you. If they do, then find ways to share your wisdom through conversation. If they choose to not talk to you, then trust your coworkers give them the wisdom.
Don't waste too much mental energy on it because ultimately, if your work is good, it doesn't matter your attitude towards new people as long as you're not going out of your way to alienate them
Thanks for the comment. My wife and I have agreed to start having kids in a few months, and I've just had a lot of things swirling around in my head. I'm excited and anxious at the same time and what I would do in certain situations. But I love random moments where you can be helpful and not threatening. Due to the time period I grew up in, that post 1950s belief that you have was not trained into me.
For example, I'm a 36-year-old white guy. I got my wife (who is awesome) and my 3 dogs. There's this one little girl that my dogs absolutely love, and she loves them too. There were small interactions with other kids around (I had to yell at the older kid because they threw shit at my door. If you need clarification on my logic, I'm happy to explain it), but she immediately locked on trying to figure my dogs out. I don't her I had no problem during the summer if she came and helped me with the dogs in the morning and evening, I was going to pay her $10 each time she helped, but I needed to meet her parents and talk to them about it first
I didn't hear from the kid for a while, and eventually, I unintenially bumped into her dad. Long story short, he told me to stay away from his daughter.
I was disappointed but also understood where he was coming from. However, I also believe it takes a village to raise a child, and I'm trying to consider which direction I feel I would go...
