I have stopped with the masks, including the bts, 7-11, and malls.
The thais dont seem to mind or move away from me. So if they want to keep them on up to them.
A lot of thais I talk to say they are still afraid, and others dont want to wear them, but wont buck the trend.
This not wanting to be the first to be different, is just the way they are.
Other peoples' opinion of them is more important than doing what they themselves want to do.
