oh gosh, let's see... that'd be a girl named Kathleen back when i was in 2nd grade, so 8 years old? i was standing up on the school bus to get off at my stop and she pulled me down onto her lap by my backpack and kissed me on the cheek and that... awoke something in me, lol

fun fact, i got to come out to her as trans many years ago and she was super happy for me and supportive! :-)
