I am at library now...hoping to finish my upper limb notes by tonight...really hope I can make it...(doubting it,it is tooo many notes d...>.<)

will be going to start my revision after I finish this post,just a super short post only...
wont be taking a long time

When I was checking my Facebook updates at library computer lab here just now,suddenly there was a Malay girl A asked the another Malay girl B who was sitting in front of me a question...(in Bahasa Melayu)
A:wei,got how many days ar in November?
B:wait ar...
A+B:(they were both counting their metacarpalpharangeal joint)one,two,three,four......ten,eleven
A:eiiii~~31days or 30days ar??
B:don't know wor.......

WHAT THE FCUK!!!!I really felt like killing them on the spot that time!!!=.=
by counting the joints also don't know how many days in November?!
No wonder la,my mum always told me that being a Chinese or Indian always has its own benefits...can eat pork....(which help in development of the nerve system)

Hope you enjoy the story...^^ (based on real story ok!no cheating....no tokok tambah!)
