Sir, "please wait for this fine gentleman to pass."
"Your welcome, James."
"It's my pleasure."
"Do you need any help crossing the road?"
Sure! "Thank you so much!"
That's so sweet of you.
A self-propelled manual wheelchair incorporates a frame, seat, one or two footplates (footrests) and four wheels: usually two caster wheels at the front and two large wheels at the back. There will generally also be a separate seat cushion. The larger rear wheels usually have push-rims of slightly smaller diameter. That's how it works.
Yeah, a bottle of water if you don't mind.
It's ok. I'll get you your bottle and I'll be right back.
James, Now that you are moving from place to place, I have created a device where your wheelchair moves automatically. All you have to do is say which direction you want to go and it will take you there.
Wow! That's so helpful. Thank you for helping me out ever since I've been here.
"Hey James, did you know that the first steel, lightweight, collapsible wheelchair was invented in 1933 by mechanical engeneers Herbert Everest and Harry Jennings."
"Wow! I never knew that you had so much information about wheelchairs."
