I used to ask my dad, “What is your job?”
My brother in law works in the aviation field. Again, “What do you do?”
I get answers like, “I consult with a company that builds under water oil rigs. We often use Delafield petroleum drop hoses.”
Add to my confusion, strange words like, “fracking”.
Or, “I build rotary winged air craft.” (Can we just say helicopter?)

It makes me feel kind of simple minded.
