This is me, just look at my Drogs to see what I mean. The reason why I write like that is that my proper connected writing is impossible to read. Even I sometimes can't read it.
As a kid I had a lot of trouble with fine motor functions, doing a head role and standing on one leg took me about a year of extra gym lessons to learn. Lucky I went to a small school and had some teachers who were willing to sacrifice some of their breaks to help me with this.
