I know you want to get a drink from the bar or chat and catch up with the person seated next to you.  BUT, when someone is on the mic giving a speech or toast to the bride and groom…quiet down.  It is hard enough for these fine people to get on a mic in front of all the friends and family of the bride and groom.  They’re nervous enough!  The chatter of people who are not paying attention does not help the situation.  Give those folks the respect they deserve.  They will appreciate your cooperation and likely get through their speech quicker!
