Rain as a whole is lovely.

Although rain which is like hail is horrible, every other type is great.

As HoH said, it's great to play football in the rain - especially if it's the type of rain that soaks you to the skin as soon as you step outside. You know the sort. Gets you so wet after a few minutes that you can't get any wetter, and actually keeps you pretty warm. Plays merry hell with glasses, though - you can't wipe them because they smear, and you can't wipe them anyway becuase they'll be covered in rain as soon as you put them back on.
