Why 4.5? Why not 5?

A lot of my friends asked me how many days leave I take for my trip. When I told them I took 4.5 days, they started to ask, why 4.5 and not 5 days? Why take that half day?

Actually I only plan to take 4 days. What about the 0.5? Well, when I apply leave that time, I realized I still got a half day leave left. I don't remember when or why I took the other 0.5 day but I just don't like to see that half day so I applied another half day lor.

I don't like to take half day, why? You still have to wake up early, you still have to stuck in the jam, you still have to pay toll and petrol, and you still have to pay for the car park. So why take 0.5? right?
