Product manager: build us a recently viewed and bookmark feature!

Younger-Me: But every browser already has a bookmark feature and a recently viewed (history) feature and its much better implemented with much less overhead.

Product manager: I don't care. Give me this feature, you are supposed to do as i say and bow.

Younger-Me: I'll take it as a challenge.

--- two weeks after feature is deployed ---

Product Manager: 😁 See! Many users are using the feature we built *shows me messages from subscribed customers*

Me: 😨 I'll never underestimate user's stupidity again.
