What makes a style?

ok ... im having what I consider an itelligent moment ...
(work with me here!)
I was thinking .... surely an aikido style would be that of the practitioner ....
i mean .... im only 5'1 ... so I have to adapt my techiques slighlty to use on say a 6' Uke .... and adapt again when with the juniors ....
so what im essentially tyrying to say ... is that everone has their own style ... ???
ok ... i THINK im done ....
clever moment has passed!
