Girl selling a magazine

Selling a magazine,
the corner by the bakery,
black scarf about her head
no matter what the day.
Walking passed each day
rarely buy and guilty,
two quid is all she asks,
calls me sir,good day.
This day I changed my mind
turned back to buy her paper
lose my guilt and shame,
but she was gone.
Have not seen her since,
next time I'll buy,
maybe then she'll stay,
if she comes again.
