It's an old and ironic habit of human beings to say 'it's not me right?' when they realised someone has been taken for granted.

Just like how the disciples reacted at the Passover meal when Jesus told them he was going to be betrayed by one of them.
'Surely you don't mean me, do you?'

It's ironic how one can attempt to point fingers at others instead of doing self-reflection.

Matthew 7:3 says 'And why do you look at the splinter in your brother's eye, and not notice the beam which is in your own eye?'

It's ironic that everyone's biggest complaint is not receiving enough, yet nothing is more terrifying than taking someone for granted.

It's ironic how your good friend can be so insensitive and tactless.

It's ironic how you started off as good friends and ended up bearing grudges.

It's ironic how a friendship can be worth less than 50 bucks.

It's ironic how one should still try to be nice to the person who has taken you for granted.
