Good topic Soror:
Hey everybody.
I would think it would be difficult to bond with a REALLY BIG line (as Soror Reds put it, like 50+). I wouldn't go so far as to call them paper because I've seen lines of 2 that are "paper...and as Soror DST Love put it, you really don't have a choice in the matter.
I was #14 of 18 and we all are in contact on a very regular basis and have reunions every year. With our line and also a Chapter reunion on our charter date.
The line immediately following mine, for which I was Dean, there were 23 of them. They are all pretty tight as well. I will agree that some factors that may influence the bonding is the length of time of the process and the "activities" that are put before the women/men. Special effort has to be put into providing them with experiences that will allow for bonding. I know it falls on the women (primarily), but I have seen situations where people are so busy running people around that the women have very little time to themselves to bond/study/whatever else.
With lines of 75-100 (I've even heard 150+), I think it would be hard to really bond with everyone. Even in so far as knowing personal information about one another...we won't even discuss passing messages
Just my opinion.
