Tips for living alone:

1. Do not hard boil eggs while you are ill and tired.
2. Make sure the batteries work in your smoke detector.

Result of ignoring tip #1 but not tip #2:
You forget you put two eggs in boiling water and doze off. All the water boils away and the pan begins to smoke and sets off smoke alarm, which alerts you. Luckily the only mess needing to be cleaned is the exploded eggs that are now splattered all over the walls and cabinets of the kitchen.

Oh, and the smell, don't forget the horrendous smell.
