I hate working in groups...

I'm feeling somewhat left out from everything, and it's reinforced when my groupmates send out an email with the following instruction:

- Attire will be business casual (no jeans, T-shirts, or hats)

And I don't have much in the way of business casual, and they set out this requirement too late to get something to work. *sigh* Sometimes I really wonder if my group hates me or something. :P
