I had aspirants like that as a collegiate and know some like that as an alumnae.
I understand being nervous and awkward/saying and doing dumb stuff because I was TERRIFIED as an aspirant despite the fact that so many Deltas were my closest friends.
But, after you give someone nice hints or teach them through silence, it is their job to put on their grown adult pants and THINK before they speak and act. At the same time, when I see an awkward aspirant at an event or at work, I ask myself "where did she get that from? I'm sure a member told her that was cool or she read it somewhere." I can't be mad at her because she did some kind of research--and it isn't her fault that SOME members like her approach while OTHERS don't.
