A reception is scheduled from 6-8 pm.
1. The bride and groom should be available to greet guests from 6-8, saving things like cutting the cake and the bouquet toss until after 8.
2. The bride and groom should leave right at 8. They've got better stuff to do! So, if you want to talk to the bride and groom, be sure to be there at least a half an hour before the scheduled ending of the reception.
And just for fun, what are your opinions on cutting the cake? Should you smoosh it into each other's faces, or should you treat it with respect and do it nicely? (My grandma was insistent on the second. "It's your first act of service as a married couple. You should respect each other!")
