quarrels.

The onset of the 1st quarrel marks the threshold of any relationship.
It's really smgth worth celebrating.

You wun quarrel with a stranger,
I can't be bothered to.
You wun quarrel with just anyone,
I have better things to do.

quarrels occur if the person mean smgth to u,
quarrels occur if he/she has the ability to hurt u.

I dunno abt d rest,
but I quarrel only if I love u.

So if I ever do quarrel with u my dear ones,
count your blessings...
-I actually quarrelled with u.
