"Aasan nahi hai tumse pyaar karna, lekin tumse pyaar na karna, usse bhi zyada mushkil."
It's not humanly possible to like every single thing about a person, no matter how much you love them. Everyone is made of both - the good & the bad, & love is just the invisible knot that ties you to both those aspects of a person.
People have their own set of quirks some of which make you laugh while others make you furious. But when you truly love someone, you accept them for all that they are. You can't measure what you like or don't like about them; you just wholeheartedly love them, inspite of everything, because all those qualities make them the person they are, & you're in love with that person.
"Isi ujaale ki tarah ho tum humari zindagi mein, aur jitna pyaar hum tumse karte hai, utna poori duniya mein koi nahi kar paayega."
