I went to bed a little before midnight. After 1:00 I woke up enough to hear my mother go into the bathroom. Next thing I know it’s 3:30 and she’s in the bathroom. I knocked on the door but it took a couple of tries before she responded.
The question then is this: at 3:30 was she in the bathroom again, or was she still there from 1:00. We may never know. I just know that it’s 3:45 now. I can hear her moving around in there, but now I need to take a piss.
