<human>: Today I was  out at Walmart with my sister, I took her baby for a walk to the game section to (you guessed it) look at games. While I was there the baby (let's call him Scooter, that what I do anyway) fell down and starting crying. No big deal,Scooter was fine. Nothing worse than a normal person tripping. But a fellow shopper started yelling at me to take better care of my kid.At first I was like, "TF? What is he talking about, my kid?"Then it hit me, I'm a teenager and I guess I look old enough to be a teenage mom. Eventually the shopper got the management involved, he lied, saying, "This Woman left her child, crawling all over the store. If it wasn't for me, he may have killed himself pulling something heavy onto him." Now obviously what he said was bull, but since I was the accused the manager believed what he said. Eventually, I was able to explain myself but only after a  30 minute trip to the security guard's office, and my sister coming in to tell him I'm not the mother.

Give me a shortened version of the text
<bot>: A guy thought my baby nephew was my kid, lied to the store's manager to get me in trouble. Had to get bailed out by my sister (the real mother)
