English is a very idiosyncratic language; especially when idiots (self-proclaimed) like me use it. Here is an example;
Me: Time for spot of lunch
Thai friend: Spot of lunch... ?
Me: It's just a turn of phrase.
Thai friend: Turn of phrase... ?
Me: Never mind.
Thai friend: Never mind what?
Me: I am going to have lunch. Are you coming ?
Thai friend: Of course, I am very hungry..
Me: Facepalm.
