You are either present or absent.
The acceptance, or otherwise, of an apology changes the fact of attendance or absence not a single jot. A vote to accept or otherwise is entirely subjective and pointless since nobody will ever bother to check, or likely even really listen, to the reason for apology.
Please accept my apology, I have abducted by aliens and subjected to obscure sexual experiments.
Apology accepted.
