to the young moms that use the metro transit system. please learn how to operate a stroller before getting knocked up. I have consideration for moms bringing up children in this day and age. Especially single moms with little support from anyone. I was on a bus and people were willing to get out of the way for the mom and her stroller but she still insisted in parking her stroller with her child in it in the doorway at the rear of the bus blocking anyone getting through or out. mainly cause the driver could not open the door with the stroller in the way. We are asked to move to the back of the bus and we do only to not be able to get off the bus at our requested stop.Please lady use your brain, or stop having children till your brain cells start to work again. —smart mom
