When their mother passed away from brain cancer a few months ago, 28-year-old Chloe Sexton became the sole guardian to her little sister Charlotte. Since her little sister had never had a big birthday party, Chloe set out to plan one for her, but only one child from Charlotte’s class responded to the invitation. Chloe posted a video to social media airing her frustration — which went viral — prompting dozens of people to come out to help make Charlotte’s birthday party a life-changing event.
