DARK PATTERNS

I remember a time when I was younger I used to use my mom's phone to watch videos or look something up for school before I had my own phone. I remember I was researching something for class on a sketchy website with a lot of ad pop ups. One of them being for something that a little kid my age would want. I forgot what it was but I remember it saying that if I wanted to get this item i would have to hurry because one the time ran out it would be gone. I ran to my sister's room and begged her to get it for me. She told me she would buy it for me when we went to the store and I was okay with that idea. So I exit out of the ad and forgot all about it the next day.
