Is it weird that 2 people don't appear to shower daily?

I often hear them go to the bathroom brush their teeth, 8 presume wash their face. But I never hear water running long enough to say it's filling the sink or a shower.

They both have a hair washing day after 2 weeks but that's the most I see of them washing.

I hear spray deodorant being used, they wear clean clothes but their room smells.

They eat in there, spend all their time in there and they keep the door shut.

Am I being weird..? I know I should mind my business but I find all this weird.

Especially because I shower or quick wash every day.
