Warning:  Tissues necessary.

Twenty-eight-year-old Anna Greenberg got to know her biggest celebrity idol, Bette Midler, while she battled cancer. Bette even sent her to LA to see the premier of her movie "Parental Guidance".

Three days before Anna passed away, she received a phone call from her idol. They chit-chat for a while, before Anna asks Bette to fulfill a dream and sing "The Wind Beneath My Wings" to her. (She asks Bette around the 4:27 mark....)

(For whatever reason, this video was recorded upside-down. There's a tribute page to Anna that has the song "Upside Down" on it, so it may mean something to Anna.)

This is an incredibly moving moment...and a reminder to be grateful every day.
