What do you mean, waiting for you for a long time to get new clothes?

I haven't been with you for a long time. What is this? A story in Shi Shuo Xin Yu? This is what the hero's son said to his friend, because he left before his friend arrived at noon. It means that you waited for a long time and left before you arrived. There seems to be a brand of clothes in the back and in the front.
