A friend and I got in a petty argument. She was talking about how when she was growing up, her older siblings would pester her, having 5 older (half-siblings) I laughed, and said "I know what you mean." She scoffed and said "No, you really don't..you're basically an only child. You have half siblings, not real siblings." I did my best to correct her, and tell her there is blood, I've known them forever, etc, but she still insists, I have no idea what real siblings are like. I know this is very petty, but it kind of ticked me off.
