I am awful at swimming cause I'm getting tired really fast. And the main problem is that I think I travelled a lot because I'm tired but, in fact, it's only several inches!
I can swim for as long as I remember. It's always been weird to hear about people who can't swim. It's like hearing about people who can't ride a bike.
I am one level away from being able to be a lifeguard so I would say I can swim. We were taught how to swim in school growing up and I have had a pool in my backyard my whole life so have plenty of experience.
