Meet Danni, who posted up a Tweet she figured would just stay within her social circle. She pledged to donate to St. Jude Children's Hospital based on likes and retweets, thinking it would be an affordable amount.
What she DIDN'T expect was for her Tweet to go viral -- and when it did, she capped the donation off at $40,000+ -- which some angry people actually chastised her for. Check out what went down below.
(BTW, AMAZING job bringing awareness, Danni! You're one of the good ones!)
