Yekke2- I have never spoken to you but from these posts I have to say I loveee your answers and how bluntly you state them. Right on chabibi!!
Sparkly- I’m taking out a point that no one touched upon as of yet. You say that you would want it to be a shidduch for u .that meqns u have feelings for this guy. I don’t think saying hi is assur but you might be doing it in a flirtatious way or trying to Catch his attention being that u like him.
