...of toilet paper and relationships

I just had an experience that summed up my relationship better than words ever could.

I went to the bathroom and realised we were low on toilet paper. So straight away I went to the cupboard to get some more so the next person to use the toilet [presumably Phil] wouldn't run out half way through. Phil had noticed before me that the toilet paper was low, but waited until he was going to the loo again to do a refill.
