Mine too, and myself, sometimes. If I am trying to make sure that nothing I say can be taken out of context, I'll be more careful about which words I choose. I look very blue collar, and dress the part, but as of today, I hold a bachelor's degree.
My husband is the same way. He speaks like he's educated, because he has learned that more people are willing to listen, if you sound smart. Maybe that is Dylan's dad's thought? More people will listen and hear about Dylan if he sounds like he is well-educated as opposed to if they had to listen to him talk like a regular Joe?
For all we know about Dylan's father, he could be extremely well-educated. We don't know very much about anyone in this situation yet.
