i understand that you dont get it.
It would drive me mad not being able to read Thai.
95% of Thais dont speak English, I like being able to socialise with them. They are a lot more fun. And more high quality women, not the Pattaya types who have been soiled by farangs.
And as far as obnoxious, it means rude. I can politely ask for things, you just grunt and point.
