I think its only polite to at least reply to ppl's sms when they askin a question and not simply ignore it.. letting people to wait in vain..
If you wanna save your sms.. fine with those that is "ok" kinda msg.. but not when people is asking you something.. waiting for your reply..
I was once a biatch who don't reply sms and I totally understand how they feel.. so now karma is hitting on me..
coz i see people following my footsteps.. :(
