DH and I recently moved in with his parents while we wait for our house purchase to go through. To be clear, we're not freeloading - we're paying rent and contributing to household expenses in other ways, as well as buying our own stuff as usual.
MIL is lovely, I've always got on well with her so living with her is no problem at all. FIL is another story. He's the sort of person who is never wrong, never apologises, knows everything, would argue black is white, talks over people etc. (Fortunately DH took after his mother!)
FIL and I are the only ones working. I work M-F 9-5 and get a bus to work from their village, which takes about 30-35 mins depending on traffic. The buses are every half hour so to be sure of getting to work on time, I've been aiming to get the 8.00am bus which gets me to the office with 10-15 minutes before start time to get logged on, make a cuppa etc. Perfect.
FIL works as a sort of delivery driver and has variable start times, but usually leaves the house around 7.15-7.45am, and obviously has a certain amount of flexibility as he's using a vehicle and can pretty much plan his own routes. This is where it gets petty and annoying. They only have one bathroom, and no matter how carefully and clearly I try to arrange with FIL each evening what time we can both use the shower the following morning without either of us ending up late for work, he always manages to be in there when we'd 'agreed' (or so I'd thought) that it would be my turn. It's not that he didn't understand or got confused; he makes it quite clear that he's just "changed his mind" or "decided to have a shave after all". Three times now (in two weeks) I've ended up missing the bus and being late for work. My manager is reasonably understanding but we don't have flexitime so sooner or later I'm going to be in trouble if this goes on.
It sounds ridiculous but it's really stressing me out! I've tried getting up stupidly early and getting in before him but it's as though he listens out for any sound from our bedroom - whether it's my alarm, or just me moving around as I get up (creaky floorboards etc) I'm not sure, but he literally races to the bathroom and practically shuts the door in my face with a smug grin. DH has tried having a word with him and he's got nowhere either. I honestly don't know how I'm going to cope with the 6-8 weeks+ we've got left here.
(Dashing off to a hospital appointment shortly so if I don't reply, it's nothing sinister.)
