The iMessage dot indicator lets you know when the person on the other is
ignoring typing you, which can be a wonderful thing. It can also be one of the most annoying things in the world when you see someone start to type and then stop, or supposedly “type” for a long time.
Here’s a mischievous little prank you can play on unsuspecting iMessage users. Go to the website below and save the GIF to your Camera Roll. Just send it to random people and watch frustration ensue. Rinse, then repeat. You’re welcome.
