Walmart!!

So just for the record I do not shop at Walmart unless I really have to that usually means I have more then one kid with me and I have to get a variety of things that I can't get at HEB and keeps me from bringing my kids all over town so with this said I am so SHOCKED each time I go!!  I always tell my sister in law that there are major FREAKS in Walmart and each time I go that seem to get closer and closer to me!!  What is bad is I usually have Emma and she just smiles at these people which then they think they can come closer to her and talk with her and I am like REALLY people just wave and walk by don't come to us and talk to us!!  Well yesterday  I thought we were doing great was getting a few things and checking out and all of sudden he shows up and I was like on lord please don't touch Emma or talk to her!!  He was so dirty  had so much hair on his face that I barely could see his eye so I tried to hurry up and get out!!  So he started talking to Emma and she was just looking at him like oh my!  So I have my back to this man and all of a sudden he starts talking to (really I am not sure if it was me or the cashier) us and telling us have  you ever boiled eggs and had them explode and I was like oh lord!  He tells us that he boiled some eggs for lunch and went to eat it and it exploded in his mouth and it made his lip swell up and so by this time I am like are you really telling us this!  I had my back to him at this point trying so hard not to bust out laughing and he goes to tell the cashier you want to see what the inside of my mouth looks like!!  REALLY!!!  Holy freaking camel crap!!!   He opens his mouth shows her the sore and tells her green pus has been coming out of it all day and it hurts really bad!!  I about lost my lunch!!  I am thinking if this just happen nothing should be coming out of it already so there is other issues besides a freaking egg exploding in your mouth!!!  So really and truly I just don't understand why people that shop at walmart can't be normal !!! I mean really!!!  I am still just so amazed at what people just feel free to tell you!!
