Embarrassed Breastfeeding At The Mall

Omg! I can not believe what happened Saturday. So I brought my three month old and 4 year old with me to the mall. I was exhausted and the baby was crying so I sat down by a fountain and started breastfeeding him. Just then I notice a man staring at me. It was super creepy and I was tired and pissed off. He walks over to me and goes "Ma'am". I go "If you have a problem with this don't say anything. My son is hungry and I will feed him how I fucking plz". He has a calm look. Raises his pointer finger and goes "Ma'am, your son's in the water fountain". I turn around and my 4 year old took off his clothes to search for coins! He was literally right next to me a second ago. I turned around to apologize but the man already left. I got my kids clothes on and decided we should go to. God I feel bad.
