I had that experience for a while at Bangla....their weekends
were on Fri and Sat.
So it was a interesting experience preparing for weekend
getaways on Thursdays and TGIF wasn't quite as applicable.
And back in SG, friends and families were relaxing on Sunday, I
was at work!
Besides that, as long as your work is inward-looking with little
dealings on a foreign-basis, its really not much of a big deal.
