We in my Alum Group call this the 80/20 syndrome!
80 % dont do Sh*t and 20 % do!
If you are in a small chapter, that makes 3-4 people do the work while the others sit on their asses!
If that is the case, then it is time to have a bitch out session!
I am also sure the same happens with all of these 100+ Groups! Just Who Does The Damn Work! Easier with a larger Chapter, probabally not!
