Getting "Stood Up"

[FAUNikki]

Recently, this last week, my sorority planned a really nice social with one of the fraternities on campus. I wont say the name of the fraternity, but I dont think what they did was right. The night before, their social chair contacted ours and said that the school was having a concert for a local band and that some of his brothers may leave early for it. That was fine. We bought chips and drinks and made decorations and everything. The next night, not one of their 60 brothers showed up. Is there something that can be done? Said appropriately? Aren't there rules governing those type of things? Nobody contacted us about cancelling it. I am thinking that they may have cancelled because we are the sorority that "doesnt put out", excuse us for being that way, but anyways.... Has this ever happened to anyone else out there? I am just curious! The night before they even had a date auction funraiser and we all showed up to support other greeks on campus. HElp Help Help!!!
