I searched in the internet for that, and there was none!
Luckily, I remembered watching the tv program 3R , ada Rafidah Abdullah, Yuen and 2 others.
There's an episode showing the ways of handling/walking the blinds. Can't remember much,
but that's what I've tried on a blind man last week.
These are the points that I watched in 3R :)
1) Remember, pegang siku nya, bukan stick-nya!
2) Satu je ingat :(
3) Sorry ....
tried black coffee, forgot that it's very 'black'.
