The Unintentional Thumb

When you're on Facebook Messenger and you accidentally hit the "thumb's up button, usually at the worst possible time.

It's going to look something like:

Person: "I'm having a really rough day"
Me: "What's wrong?"
Person: "My dad passed away. 😰"
Me: "👍"
Me: "Goddammit! The unintentional thumb strikes again! ...sorry for your loss."

Example two:
Person 1: "How are things with the hubby?"
Person 2 :"I found out he's cheating on me."

Person 1: "👍"
