I had to look up Tejano. Is it pronounced Tee Jan Oh? (I was a tossup. Go to Oxford to study Eengleesh or ask questions on Azzgab...) As for wearing gowns- are we talking dressing gowns around the house, or high class evening gowns in public?
Given your rotten streak, I'm surprised you did not bake him some Vincente Fox cookies...
It is tayHAno, means in this case his family is old, goes back to before 1840 or so in Texas, not recent immigrants, even though they have Spanish surnames. They are the Texan equivalent of the DAR or Daughters of the Confederacy, society snobs. His dad was some muckymuck in politics there, hardly saw him at all, I had to tie his ties for heem 😂
Now he is gay-married to some old fatty in Denver where he moved to be a lawyer 🤪 he had a little tummy when I knew heem but I bet he is full-on hawg now.
Academic gowns are like what we wear for graduation, they have to wear them to eat in one of the dining halls there.
