Hyacinthoides, the stranger and natter.

1. The smell of bluebells. Katie bought me a bunch from her parents' woods. They smell like hyacinths but less vulgar and overbearing.

2. Going out with a crowd of people you don't know very well because you don't have to worry about their personal problems.

3. When people (i.e., Katie) turn up for a cup of tea at half past ten at night.
