Pat Springer didn't expect to do anything too crazy for her 70th birthday Saturday, but her daughter Erica Roberts had a special surprise planned her mom never saw coming.
Roberts gathered 70 of her mom's favorite flower, carnations, and 70 messages from family and friends. Pairing the two, she kept her mom busy at the mall while she gathers 70 strangers to give her the flowers and wish her a happy birthday.
The planned "Flower Flash Mob" completely took Springer by surprise. She says she enjoyed having all of the strangers come up to her to wish her happy birthday, and in some cases, giving her hugs.
