Do you talk to your kids like a teacher?

I was listening to a dad talking to his kids recently, just happened to be standing nearby. He talked to his children like a school teacher with the same forced friendly tone that you would expect from a kindergarten teacher or miss Rachel or something.

I am more direct and I generally use a natural tone and attitude. Sometimes I’ll get frustrated with the kids and speak more sharply to them.

I would like to be more patient and “friendly” but its not natural for me so I feel like I’m acting. I can’t imagine being “on” for all of the time I spend with the kids.

I have for the most part talked to them in an adult tone since day one. I’m not sure what is the right way to do it.
