My first fluid lab

Today is my first fluid mechanics lab. Made some new friends. Most of them thought I failed the class, so I had to repeat it. I've lost count of how many times I've said , "No no no, I haven't taken this subject. Which is why I'm taking it this sem." Duh! I'm totally cool with it I guess. I have to admit, at first glance, I do look like a bimbo. So I don't blame them for thinking that I'm repeating the subject.
