An elderly lady was walking

An elderly lady was walking
Stopping often
Holding on to a fence
Breathing heavily
Her winter jacket
Moving up and down
Up and down
Up and down. 
She looked up for a second
Maybe she saw me
I think with my eyes I asked her
All the way from the sixth floor
Do you need help?
She went on
Stopping often
Holding on to a fence
Breathing. 
I think it was the mask
And there was only one other person around.
