<human>: A while ago, before our University convocation schedules were out, we said that we would attend eachother's convocations. Mine is near Vancouver (far west coast Canada) and hers is near Toronto (far east cost). Vancouver to Toronto is roughly a 4.5 hour flight, and each have about a 1hr commuter flight to/from the big cities. Right now we're both working in Edmonton which is sort of in the middle of Canada.

Well the schedules came out today and mine is on June 9th, while hers is on June 10th. She was very happy to hear this news since, it meant that I could go to her convocation after mine. The thing is, I had envisioned a week apart between the convocations. I want to go out for dinner with my parents after my convocation and then go party with my university friends, who I will probably not get to see again for a very long time. 

I told her that it wouldn't work out, with all the travel times (including waiting around at the airport) and that we'd just be tired and that I wanted to go out and hang out with my friends instead of rush to an airport and criss-cross across Canada.

She didn't take to this kindly and is VERY upset at me. She won't speak to me now. 

How should I approach her? I feel that she's being irrational here. I don't feel that it's fair that my parents wouldn't get to take me out for dinner and that I wouldn't get to party with my friends one last night, while I would be flying across the continent to go party with her friends that I barely know. I don't want to be robbed of an experience here, but she is VERY upset. I'm leaving out the issue of travel expense too which I haven't brought up as I think it would make her more upset and my previous points were good enough to make my case. I did fly out to see her in December which cost about 800 bucks which is A lot for me, while she didn't come visit me during our semester apart.

Can you give me the gist of the text in a nutshell?
<bot>: Girlfriend and I have convocations one day after another, and she wants us to go to each one, but I don't want to rush across the continent on my day of glory.
