Why did this woman called me weirdo?

Anonymous
I saw this mom at the park with her two kids pushing the stroller I approached her I told her the kid's feet could get hurt and I went on telling her my daughter was taking the dog for a walk. She give me mean look as if I made her feel uncomfortable and called me weirdo ignore me and she continues walking pushing her two kids with the stroller why didn't she made conversation with me?
