I live with someone who has IBS, which means most mornings they are around an hour in the bathroom (going to the loo, and then having a quick shower). It is a source of stress for me as I hate being late, and if I hear them going into the bathroom I know that is an hour+ that I can't get in there to get ready. As a result, I often get up super early when needed. For context, we have a downstairs loo they could use to go to the loo, and then just shower upstairs, but they prefer the upstairs bathroom as there's more privacy.
This morning I woke up at 7am to get ready for work at 8am. I work from home, but today I'm starting work at 8am rather than 9am. I saw I had been send a text in the middle of the night when I was asleep from this person, to say they needed the bathroom at 7am, as they also start work at 8am. They work on shift work so their schedule is all over the place, so it's hard to know when they need the bathroom.
I went and spoke to them and asked if they could go to the loo downstairs before their shower, to give me 15 minutes to quickly shower and get ready and they said yes. They then stayed in bed until 7:10 and came banging on the bathroom door saying they needed to get in there as they were going to be late.
AIBU? I know I technically used their 'slot' in the bathroom, but I did ask if they could go to the loo downstairs so they wouldn't need the bathroom for a full hour. I'm being told IABU as I work from home and they work out of the house, so it's more important for them to be ready on time - which I get, but I did ask first if I could go in the bathroom
