Why does my yoyo come back to me when it is not auto return?

Question

all i did was open it to untie a knot

Answer 1

Maybe your string it wound up too tight at the yoyo base.It has to be loose to sleep and do tricks while it is spinning.

Then you can walk the dog,and every thing else. Try that.

Answer 2

That is how it is designed. It's called the laws of physics. Either that, or you have a ghost messing with your Yo-Yo.
