oh wow...I wish I would even "had better-ed" my momma...
um, since she didn't have the time to *politely* let some member of your sorority know that, although she was interested, she wasn't able to come to the informational, and esp. since she didn't have the time to wait for the information she so rudely requested, you might not have the time to call her rude behind back!
How interested is she if she's going to wait 3 weeks after the meeting to request information anyway...
However, if you would still like to call this girl, I would calmly set her straight...and if she can't take the heat for her own actions she should stay out of the kitchen
