Grandmother has neighbor kids over for tea, only one shows

Hi, I am looking to find a movie about a grandmother, elderly woman type, who invites the neighborhood girls over for tea, or tea party, and only one little girl, out of 4, show up. It’s a sad movie and teaches kids not to lie and make false promises. It’s an American movie. I viewed it in 1988 in kindergarten but it could have been made earlier. I would love to view it again! Thanks! -Julie

Got something to say?
