apushatayid- my school did that, I don’t know if you’re referring to the same one.
Actually, at the wedding of one of my closest friends, our elementary school principal was there. Another one of my friends taught in that school. The principal was walking around saying “IY’H by you” to all of us, and my friend whispered to me, “Notice how she didn’t say IY’H by you to me…”
In the end, my friend got engaged in April of that year and didn’t get married till well after the school year.
