13 cards

receive cards from a joker. birthday is on feb 29 and since 13 is one more than the total months in a year and my bday is one more day in feb every 4 years...he thought he was being funny. I was 13 if you count the amount of 29ths I've lived through. in reality i was 52 but since it was feb 28th and it wasn't leap year..he thought he was funny. every 3 out of 4 years he does this. You don't know this person.

The cards are from variations of frog names...leaper, kermit, jumpy, ribity, tapoleon, hoppity, froggy, hopper scotchee, scott hopperson, kermit de leaper......

the from name on envelope was just first name but as reading the cards....had the froggy last names.
