Shower in the morning, sink in the evening

Pros:

• if you are in a rush you can save time by scrubbing yourself and brushing simultaneously
• any spills are washed away immediately, leaves the sink clean of toothpaste splatter
• you get to stand under the nice warm water for a few extra minutes instead of standing in front of the sink, staring at your tired self in the mirror while doing your brushing regimen

Cons:

• apparently women don't really care for the concept so be aware of that lol
