2 people, 1 bathroom - How to Survive

So one of my friends will be having a house guest next week for a couple weeks, but his place is sadly not a house.  Instead he lives in an one bathroom apartment.  So he jokingly asked me: how will I survive?  Here's what I told him...

• Don't tempt fate: if you are leaving a place and think you can make it home before using the bathroom - Use The Bathroom!
• Shower when you agree: it's easier if one person showers at night and other in the morning.  Pick a time and stick to it.  Don't change it day-to-day.
• Ensure toothbrushes don't match: the situation gets bad when germs are passed between roommates through the toothbrush.
• Store everything: just like your mother said, designate a place for everything and put it back there.  I found this is especially true for a girl and guy living together.
• Power accordingly: be conscious of when you blow dry your hair in winter (or summer).  The bathroom and one or both bedroom might be on the same fuse in older houses, so having a blowdryer and fan/heater will lead to temporary power outage

In the end... Just Survive!
