People take personal hygiene very seriously in Ireland. Sometimes people take a shower a three times a day: one when going to work, one when coming back from work and sometimes one at home. If it's a day off, or a person is otherwise not connected to work life, going out can be labeled as taking shower.
There are three types of rain in Ireland: fog, rain and water. Latter is when rain comes horizontally against a person's face and wearing an umbrella is more like a joke than actually useful accessory.
