Yes, that is a long-sleeved undershirt. I recently took a Saturday off to attend a sorority event here at Rockhurst. They took us out to the Holiday Inn at the Plaza, and it was a blast. I was really tired, so I thought the night was going to be a waste. In the end, however, it ended up being a pretty good time.
There was dancing and good times all around. Most of my friends were there, and we all just enjoyed having a night off to relax and get away from school and work.
These are the types of things that Greek life at Rockhurst can do for you. They provide you with opportunities to unwind and get away from the daily grind. You can look online to learn a little more about the Greeks here. After that, you will just have to experience it for yourself. Once you do, I guarantee you will just want to keep going back to them.
Just remember, dancing, free food, and friends. Those three things are enough to keep anyone happy for a night, and provide a good release from the stress of school.
