I'm probably being unreasonable because it's her house but this has brought back childhood annoyance so I've got to let it out here.
My period has just come and I'm going to stay at my Mum's tomorrow for the duration. She has an open bucket style bin with no lid in her bathroom. I'm also going to be sharing this bathroom with DH and tween/teen DSs. Obviously I can just get over it, women have periods etc etc. Going to get some bags to wrap them in.
It reminds me of how this bin was the bathroom bin throughout my adolescence and I had to put used sanitary towels in my bedroom bin (no lid either). I was so embarrassed 😐
