I feel frustrated because my friend and I are part of a group planning an event and they're making it more burdensome for me through their ignorance when I didn't want to get super involved more than necessary. I have years of solo event planning and hosting but stopped because it was exhausting and thankless for me. They've never hosted or event planned before, and they have been to events I've planned. It's insulting the way they're downplaying effort like making someone else do prep that they volunteered to do and glossing over taking care of other details that are important for the effort on everyone's behalf to be worth it. I had to remind them about stuff they were in charge of that they'd forgotten about. They said a "fun little detail" would be to do something time consuming / complex and not trusting my experience in time management and effort when I tell them the reality of it. I'm angry they don't trust my opinion and I'm having to make up for it so the event goes well.
