Sorry I've missed this for the past month. I don't know why my computer didn't show a new posting.
There is nothing that I know of in our bylaws that spells out a specific ceremony for pinning, engagements or lavaliering. In fact, most of the undergraduate Delts I know don't even know what pinning is. It's just not a part of their world, I guess.
That was a real surprize to me.
It's been a very long time since I was an undergrad, and I know we had a ceremony in which both chapters dressed up and we serenaded the sorority -- and, of course, the couple. I just don't remember much beyond that.
I don't know whether that ceremony was a Fraternity wide thing, or a chapter tradition.
Sorry, that's not much help. If I hear of anything, I'll let you know.
The above is the opinion of the poster which may or may not be based in known facts and does not necessarily reflect the views of Delta Tau Delta or Greek Chat -- but it might.
