Simply DON understand!

I got a colleague of mine...

Colleague A.

Collg A used to work v late at previous company, Collg A soo proud to tell me that A can stay till 10pm almost everyday.. its EVERYDAY!

But when Collg A come over here to work, A OT doesnt hit 5hrs per month.. When need to work late, I asked A to stay.. but A will still knock off at 8pm sharp.. I really don understand why A can work so late at previous coy but not current??? Very disappointed.

End up, I'm office alone here... sigh, this feeling SUX! I wanna get out of here.... really!
