I think we should sympathise and empathise with Mr Chew. Please do not laugh at him and please do not ridicule him and give all sorts of reason for his unfortunate affliction. I can tell you this: all of us, yes all of us, will never know when misfortune will fall upon us or our loved ones of our families. So please be careful when we ridicule and mock others.The spit will fall on our face and return to haunt us.
