I have this experience many years ago when i was in Paris. The
salegirl simply pulled open the curtain. I did not know what she
wants coz i simply dun know what is she trying to tell me. I was a
little shocked initially but when i stepped out of the changing
room, i realised most women did not close their curtains
completely.
Now, i will happily invite my bf into the changing room if it is
allowed. Did that once overseas when i was trying on lingerie, he
simply slipped into the changing room. If he did it
unintentionally, i would think that it is very kinky instead of
being paiseh.
