Both parties eventually apologised.
One later in the night, the other a year later
(the only time I have ever had a one-to-one conversation with her).
I didn't forgive them verbally since it would have been 
acknowledging that they had guessed correctly it was me.
In each case I couldn't help but kiss them on the forehead as a
token of forgiveness. The apologies were sincere and remorseful and human -
I am a sucker for people that reveal their humanity.
