The good point is that everyone go into details about welfare, and they thought many dangerous or inconveniently places with the viewpoint of wheelchairs in mind. The import of a statement is very good!
The bad point is that most people read English and they didn't speech in a laud voice, so I couldn't listen their information.
I think you'd better use "eye contact" and speech in a laud voice with your body language., and then it'll be more better presentation.
