My 3 Year Old Nephew Said His Mom Does Not Like Me

Leo and Rebecca Buzz Question....My 3 year old nephew the other day came up to me at a family gathering...and said "My MOMMA DONT LIKE YOU"....Wow he said it in front of the whole family. I let it go, but later it made me wonder if I need to have a talk with his momma, my sister in law. Thoughts???? I thought we were cool....
