My statement applies across GLOs (cultures). Even if XYZ got their ideas from ABC; and ABC got their ideas from DEF,** 99.9% of the time the general ideas originally came from somewhere and weren't just invented by the college students. People will say "'they' used to do this back when...I was told...." That also applies to alumnae/alumni and older members from other chapters who share ideas.
**Across GLOs (cultures), it is more common for XYZ to get ideas from other chapters of XYZ than for XYZ to get ideas from ABC.
I keep saying "across GLOs (cultures)" because grandiose and general statements are always made on GC that exclude what BGLO, LGLO, MCGLO, and AGLOs do.
I'm making a grandiose and general statement that doesn't include every instance but often applies across councils and conferences in which there is a culture of sharing information from old to young members.
