Input: This is about a group going out eating to celebrate 2  peoples birthdays.

Boba Fett: One getting celebrated
Han Solo: other one getting celebrated
Mr T: Boba Fett's oldest friend
Kodo: half of the wombocombo planning it all

So 2 weeks ago Solo's gf and Kodo texted a bunch of people about how we were gonna go out and eat to celebrate Solo and Boba Fett (paying for them). They said it was either gonna be friday or saturday. That was all info given to us at the time.

Since I didn't hear more of it I assumed it would be on saturday (bad planning on my part I know) and so I was gonna spend the friday after work at my gf. On wednesday I get told I can end work at 1 pm on friday (this never happens) so I tell the gf I can come over at 2 instead.

Last night when me, Kodo and Mr T were in discord Kodo suddenly says we're going out on friday at 3 pm (that means somehow he and Solo's gf forgot I always end work at 4 pm) and that Mr T apparently hadn't been invited. Also we're going bowling at 8 pm. I get pissed at Kodo for not telling us sooner and forgetting to invite Boba Fett's oldest friend, meaning I gotta tell gf I'll come over at 9 pm instead. Mr T get's pissed aswell having not been invited.

Later that night Boba Fett joins the call and he hadn't been told anything until then. He get's  really confused that he hadn't been told before and that Mr T hadn't been invited.

So now Mr T is invited to eat but since they've already booked the bowling, he can't join on that. Leaving me, Mr T and my gf pissed (she since I get there much later).

So am I the asshole for being pissed at Kodo and Solo's gf for doing some shit-tier planning?
