Tell Me Everything': Robert Downey Jr. Writes on Twitter to Boy Having 'Rough Day

Movie star Robert Downey Jr. made a child's dream come true Wednesday evening when he wrote to him on Twitter following the boy's "rough day."

Kathy Ellis, Aidan's mom, initiated the conversation with the "Iron Man" actor.

"It would make my son Aidan's day if you could tweet 'hi.' As you can see he has had a rough day,'" she tweeted.

That immediately grabbed Downey's attention and the two conversed back and forth.

The conversation resulted in praise for the actor online.

"My heart is melting," wrote one Twitter user.

"This is amazing," echoed another.

The tweets came after Downey made news Wednesday when he concluded an interview early after  a reporter asked him about his former drug use and father.
