As those who read my other thread would know, sometimes my back
pain really affects me and make me give a shack face to all my
commanders and platoon mates. It is so frequent such that it
happens every time where there is physical activity or parades
under the hot sun. Then some of them call me chao keng, but cant
they tell by my shack face that the pain is there? Can they go db
for this?
