Input: Text: so this happened a few years back...i was, at the time, a new father. i was really getting into the family thing and was pretty sappy when it came to kids and young families. my wife and i had a great time parading our son around and loved the compliments that others would give and liked to return them whenever i had the chance. one day we went shopping. my wife was pushing the stroller through the store, staring at this and that and i had become quite distracted by a new mother carrying her own baby around...i started smiling sappily at the baby and the mother, thinking about how wonderful it was being a new parent. when i looked up at the mother, she was just glaring at me. "what a bitch" i thought, and turned to walk away. it was at that precise moment that i realized what i had done...she was breastfeeding her child...and i had been watching the entire time...with that goofy ass smile.
