Hmmm.... 1. I will grab a book or something to cover my face, or
if I don't have anything, I'll just ignore all the stares...
2. Mmmm, I had a situation like that once, just that at least more
than 10 friends. So paiseh leh. I didn't have the courage to ask
that person to sit down, so Igot up, and walked to my friend on the
pretense of talking to her, and that person sat down.
3. See first lah. Depends on how "fallable" that old person is.
