On my invitations I have that the wedding is at 4:30.
I assumed that everyone knows that the wedding will promptly start at 4:30.
Well my FH ( I did'nt know he knew anything about weddings) said, and the DOC agreed with him, that 4:30 means that the guest arrive at that time.. that it doesn't mean that it starts at that time.
For me, if I get an invite that says it is at 4:30 on xyz date, that means that I need to be there and be seated before 4:30. Am I wrong?
