Housemate doesn't ask, she tells

My housemate sent a message to the group chat last night simply stating:

"Thursday June 11th we’re going to have a [band] rehearsal - full band from 5.30 in the lounge room. It’s an acoustic set, so won’t get loud. Should be a one-off as we are preparing for a gig the following day."

I do appreciate the heads up because she almost never gives us one, but I don't appreciate how we're being told it's happening like we don't have a choice. I finish work at 5:30 so it means I'll come home to a full house of musicians and it sounds like it doesn't have an end time so might go late (they often do).

Should the housemate ask or has she done due diligence?
