Thank you Isa! you said what I wanted to say!
I am furious that they even allowed them to get close to the altar let alone lean then sit on it?!!! Isa is right you were extremely kind to them!!! if it were me, it would have been a different unpleasant scene,not to mention the sight of me yelling of get the heck out!!!
Please make sure this dose not happen again. those who enter must enter with reverence, or not at all. do not worry about diplomacy on this case. this is not up for negotiation!
Edit : because I am pissed , @ that Choir master, tell him that it is not his mother's kitchen where he gets to play Mr nice guy. he better man up, This is the Altar of the Lord!
Lord have mercy !
