<human>: This happened years ago, but it's still embarrassing. I used to have neighbour's,  and they had two daughters. One my age (we were 7 or so), and the other was 4 years younger than us. Me and the girl my age were playing in her basement, and she said her sister was coming down, but not to look because she was naked. That seemed like a stretch, and since we joked around,  I called BS. I went to the stairs, but lo and behold, there was the girl, naked. No shirt, pants, nothing at all. As soon as I saw the lack of a shirt, I looked away and let out a half scream, half squeal. The girl my age couldn't stop laughing, and I couldn't stop running.

Give me the gist of the text in a nutshell
<bot>: I ignored my neighbour,  and accidentally layed eyes on a naked 3 year old. I'm still scarred to this day.
