I'm going to have my own schedule and ignore conflicting events
Has your schedule conflicted with other events on your calendar?
Yes, I was invited to a party, and I have a meeting at the same time, but I'm going to go to the party anyway.
A meeting is an obligation that you must meet, while a party is optional. Even though there is a conflict, not going to the meeting is irresponsible. This could make you look untrustworthy, and is worth considering!
Fuck that meeting, I'm not going to attend it because I want to go to the party.
Ultimately it's your decision what you value more.  I just hope you're aware of the potential consequences of avoiding doing something you were required to do!
