@ THANK YOU ALL FOR THE WONDERFUL FORMATIONS HERE
you're welcome
@ It does not help being 60, autistic, add, (born that way) and had a stroke at age 36 (recovered enough to have gotten a license as an aircraft mechanic)...
haaa, i like autistic people, i like the way how they see the world, so different but so beautiful people. obviously , it can be very difficult for them to live in our society with untolerant persons coming with closed eyes. My son tell me that i'm autistic sometimes :D
