I had a terrible day

I had a terrible day because 'coz (coz is for chatting, not suitable for writing ^^) I was caught shopping in Taobao while at work. I was so concentrated that I failed to notice my boss was standing right behind me. My colleague who's in the next stall tried to warn me by kicking my leg but I was too stupid to realise that. What's worse, I told him to quit kicking me. Then he looked like his face got run over by a tractor at the time... soon my boss tapped me on the shoulder and asked me to have a word with him in private. To be honest, that scared me half to death. Fortunately he wasn't as mad I as I thought he would be. What a day...
