Imperfect

My flatmate and I have a clock hanging on our lounge room wall that doesn't work. Well, we assume it does, but we haven't bought batteries for it the entire time we've lived here, five months now... It's a little imperfection in our flat that goes unnoticed by us but we're reminded of it whenever we have guests. I think we like the time, 7.35... Not too late, not too early.
