Being too optimistic

Everyone knows its good to be optimistic, but sometimes you should not be too optimistic as can be seen below.

The scenario is based on the pre-enlistment conversation of 3 Singapore Poly students (2 guys and 1 girl) who were sitting beside me on the train.

Guy A: How many camps are there in Singapore?
Guy B: Don't know
Guy A: But no matter what, we will have to be in Tekong for the first 3 months right?
Guy B: Yeah... hopefully we can all be in the same unit after that.
Guy A: Hope so... I wonder how the training is like?
Guy B: I heard you only train for 4 hours a day.
Guy A: Really?
Guy B: Ya la... who can train the whole day? No man will be able to take it.
Guy A: Ya hor... now very slack, since last year got quite a few people died
Girl: Die??
Guy B: Ya, last year got some died while running
Girl: Oh...
Guy A: So if you just cough a bit, they will probably ask you to fall out... They all scared liao.
Guy B: Should be quite slack one la, how tough can it get?


Hopefully they do not get the shock of their life on enlistment day.
