Yedah I would have done that but I wasn't sure where the towels were. They're somewhere in my brother's bedroom but if I go over there I have to go over near the bathroom so woulda felt like I needed to get a shower and if I then couldn't find the towels I'd be fucked
This (well similar) actually happened last night lol
I dealt with it well though as I was lucky - I wasn't desperate to pee so I managed to walk out of the bathroom, go downstairs and ring my mum
