Holding Hands-PDA? I need your help! ((EASY TEN POINTS))?

ok first of all that teacher is a pervert for sayin all that. wow. but anyway your kinda stuck bc "pda" means anything affectionate at all. so holding hands would be a pda. so would hugging kissing etc. for revenge i would write a very well written (like, not one i would write lol) letter to the principal detailing how this teacher said perverted sh*t to you and it was out of line to say and that you think it was ual harrment. it was. it was SICK to say all that and very unnecessary.
