Happened quite a few times already. I shall type down how my form and assistant form teachers always greet us.


[Mr Pang]: Good morning.
[Class]: Good AFTERNOON sir.
[Mr Pang] (looks at watch and clock): Sorry, afternoon.


[Mr Ee]: Come on, hands by your side, let's wish each other. 1, 2, 3, good morn-AFTERNOON class.
[Class]: Good afternoon sir.
