It is hard to make out detail in the image but...
That is a wheelchair. She probably is not able to push the lawn mower without it.
I have one that is similar, they cost thousands of dollars, run on a battery charge, and have a risk of tipping over, getting stuck, or breaking.... better to just get a riding lawnmower, if a person is only 'lazy'.
I highly doubt she is lazy. If anything, she is the total opposite of lazy, at least she is cutting her own grass, which is more than I am able to do...
And I am not yelling at you, or putting you down. Maybe you just simply made a mistake, which is fine with me... but the description of the image is a bit hurtful, just thought you should know that.
