How Humiliating! (not really)

Here's the story : I just came from eating dinner, and my parents' friends are here, for dinner too. I was too tired to change to something nice so I just wore house clothes. A plain white shirt and green shorts. I dint really mind anymore because I was thinking that they'd just be in the dinning room while I take my dinner outside. So I was just enjoying my time, pigging out. When suddenly(!), my uncle went out. O.O But then I was just like, 'Oh, well. I don't really care.' As I turned around to face him, he asked 'where's the trash can?' and said, 'Oh! Sorry', when he saw it was  me. Why'd he say that? Well obviously, because he thought I was the maid. >.< How sad and embarrassing. My mom laughed at me when I told her that. How embarrassing! =/
