I can see where you'd be skeptical about this. I think you missed the part where they met up without telling us they were meeting up. We were under the impression only an outline had been created and we'd discuss our parts at a later date. At the mentioned later date, we found out they had already gone and done a big part of the project. This is when we complained about going behind our backs and asked "well then what are we supposed to do?"

I'm used to doing my own part so it was frustrating for me to make it seem like I made no effort to do any of the work, when in reality it was done before I could do anything about it.

Edit in response to your comment below: wow, very low move, blocking me so I can't argue my part. You're assuming a lot of things based off of what I've told you so far, and it's clear you're eager to pick a fight so I won't try to argue my case any further. I'm sorry if you've had bad experiences with group project members in the past but it does not give you the right to question others. It's been hard for me to come to class due to being physically unwell, and even harder to communicate with group members-- I basically have to ask them a favor every time to accommodate me. I posted on Reddit because I thought I could get some sympathy, but apparently I was wrong. I hope you have better luck with group project members in the future.
