Let me tell you this. If you do not appreciate the effort one puts in for a group assignment or project, then you will have to bear the consequences. Pray hard for doing so. Pray hard that the person that you just infuriated has not yet reach her threshold. If once that happens, nothing can be salvaged.

Let me tell you this. If this person is tolerant with you this time, it doesn't mean she will every single time. Once you cross over the invisible line, the consequences will be getting burnt by the lava. When that happens, the only thing to appease her will be to shoulder her responsibilites and start doing something.

Let me tell you this. If you take advantage of this person for slogging her guts out whenever she does a project, well you will regret it. Trust me. You will. When she writes out the agenda for today's discussion, it shows that she put in effort and is serious in having some discussion for the project. If you do not cooperate, she does not see the reason of organising any dumb discussion when she waited for 2 hours and only one came online.

Let me tell you this. When this person is infuriated by you and she does not scold you, that doesn't mean she doesn't mind. In fact, she minds alot. The fact that she doesn't scold you right in your face is to save face for you, not to make things awkward for each other. However, that doesn't mean you can take advantage of that.

Let me ask you this, why is there an invention of mobile phones? To keep in contact and touch with others. To make communication easier. So by violating the use of the phones by not checking them frequently for any important smses, etc, you are not even fit to be in this century. So in this case, the best is sleep in the tomb and wait for recarnation or even miracle so that you can return to the older days.
