You have posted something on a group chat that was intended for a single member of the group.
That person then sends you a private message saying "Were your video and last 2 comments in the Group Chat meant to be sent to me?🤣"
You immediately go to look who has seen what you posted, only to discover that everyone has seen them.
You delete them because you had a derpy moment that everyone witnessed.
Dude, thanks for the heads-up about my post in the group chat that was really meant for you. I derpleted the whole mess.
