1. When you don't know where to stand in the lavatory.
2. When you're on public transport.
3. When you can't get reception.
4. When two of you want to sit down on the train.
5. When you're trying to advance your career.
6. When you're stuck in a date that's going wrong.
7. When you need to get out to go to the toilet.
8. And when you're making sweet, sweet love.
