Is it weird for an almost 18 year old to hang out with 13 year olds?

I'm 17 and I just graduated this May. My sister is 13 and we spend a lot of time together and are super close. She invited me to hang out with her, her boyfriend, and his friends once and I did. Now we all hang out very often. We text in a group message together everyday. I even hang out with them with out her sometimes when she's unavailable. My parents think it's weird but my friends don't (meaning my high school friends who will be juniors next year.) Is it weird or is it no big deal?
It's creepy.
That's not weird at all...

By the way, I do have friends my own age that usually come with me when I hang out with my sisters friends.

And another major reason why I hang out with them is that I don't have a car so wherever my sister and I go has to be walking distance which all her friends are within walking distance of us as are my two closest friends of my own age.
