Some take shower during the morning, some at night. I take it at night because I get dirty at work, so it's pointless for me to take it in the morning.
I've never really understood why people shower at night, then get into a bed which may not have had the linens washed in a week (or more) , sleep in it all night, and then feel as if they are a clean and hygienic person when they wake up in the morning.
Don't you think a person who showers in the night to wash away the dirt, probably has a cleaner linen that those who only washes during the day?
Two people, both go the same have the same job, use the same work commute, and gather the same amount of dirt after they get home. Person A showers in the morning, so he goes to bed straight away, taking all that dirt he gathered in the morning with him to bed. Person B showers at night, washes away the dirt, and goes to bed, The bed is cleaner because it doesn't have as much dirt as person A.
Person A showers in the moring because his bed is dirty due to the dirt he bought with him to bed the night before. Person B doesn't need to because he already took the night before and his bed isn't as dirty as person A.
