Single mothers are already going through alot of things, there are somethings you should never ever say to a single mother:
1. What is it like to be mom and dad at the same time?
First, she is not the father. She cannot be the father and mother at the same time. All she does is try and be a good mom to her kid(s).
2. How do you manage this?
Well, being a single mother is definitely not easy but you asking how she does it is insensitive. Whatever she does to pay her bills, how she manages to raise kids alone is all her business.
