Buddy's First Call (1914)

Buddy Watson, the youngest of three brothers, and just getting accustomed to long pants, meets Elsie Forster at a church social and is smitten by the young lady's charms. He writes, addressing the letter simply, "Miss Forster," asking permission to call. Elsie gets the note and joyously answers "yes," but Grace, her sister, sees the letter and is quite sure he means her.

Unfortunately the movie Buddy's First Call is not yet available on HBO Max.
