Brody Ridder, 12, had arrived home from school with a nearly empty yearbook, only managing to acquire the signatures of two teachers and two classmates despite asking for more. Ridder decided to sign his own yearbook with a note to himself: “Hope you make some more friends,” he wrote.

When Brody’s mom saw this, she was sad and angry. Her son’s message to himself reflected months’ worth of bullying her son experienced at school in a Denver suburb. Because of this her mom posted a message on their school Facebook group and her personal Facebook account. Among those to see the message, was Paul Rudd, who plays Ant-Man in the hit films Ant-Man and Avengers: Endgame. Rudd Face Timed Ridder last month and sent him a handwritten note: It’s important to remember that even when life gets tough that things get better. There are so many people that love you and think you are the coolest kid there is — me being one of them!”

Brody even received his own signed Ant-Man helmet. After sending this message, Brody’s mom is currently in talks with nonprofits that work on anti-bullying initiatives to continue spreading the message of kindness and empathy.
