One of my duties for the Yeshiva at which i work is to send out statements for outstanding pledges these can be for tuition or a dinner journal ad among many other things, there are so many of these, why do people for example say ok ill take a half page ad bill me for it and then totally neglect it until some point in the future when they will just say i never made such a pledge how dare you?
