Steal Lunch Time

I am very sleepy now. I always feeling sleepy after a heavy lunch. Today I went out for lunch with another two colleagues. we seldom have chance to go lunch like this. it would only happen when we going out with boss or the boss is outstation. We are trying not to let boss know we go out for lunch together. I have no idea why we have to be so scare of that. Maybe we do not want boss think something not good in us. Maybe she would think we are kehpohing her when lunch. haha
