When did you first figure out that you were a rider? Me, I didn't realize it at first. As I've told you in the past, I didn't learn to ride motorcycles as a kid (not even dirt bikes, to adult-me's later regret). I also didn't learn to ride bicycles super early, though I did start on those as a kid.
Know what I did try to ride when I was really young, though? My grandparents' dog. I loved him so much, and to four-year-old me, he looked like a horse. He was big, drooly, and so friendly. Very importantly, he loved me. Naturally, my grandma thought this was adorable, but she was also understandably worried that I'd hurt him if I tried to sit on his back.
So, she made me a life-sized stuffed animal version that I could sit on instead.
