i personally have an issue with it because something similar has happened to us. We hold our philanthropy ever fall for all fraternities in IFC. The fraternities know about it and usually participate. Good times. However, for the past 2 years, another sorority in Davis has been holding a similar philanthropy on the same day as ours. And they continue to invite OUR fraternities. What's worse is that our fraternities actually go down there and participate. It got so bad the first year we had to reschedule the whole event cuz only two of our own fraternities wanted to participate in our philanthropy.
I don't understand why all the fraternities on one campus would suddenly blow off one of their own sororities to participate in a philanthropy off campus.
bottom line... yeah it would bother me.
