I go to Walmart a lot, I grocery shop there, get my shower stuff there and all kinds of stuff and never had one rude encounter.. But last night we went there cause I was craving apples with the caramel dip stuff and this women who worked there looked at me and said "I hope your having a girl, you don't look like you would be a good mom to a boy "..and I kinda shook it off.. But then she went out of her way to move closer to the area I was shopping and said it again.. I looked at her and finally said thanks for your opinion but I'm having a boy and how I am and will be as a mother is none of your business. And she continued to go ahead and say poor kid.. Luckily her manager walked up at this point and I flipped out.. Why are people so rude nowadays..
