Matthew 7:3-5

3 “Why do you look at the speck of sawdust in your brother’s eye and pay no attention to the plank in your own eye? 4 How can you say to your brother, ‘Let me take the speck out of your eye,’ when all the time there is a plank in your own eye? 5 You hypocrite, first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother’s eye.

In other words...

It's easier to see the tiny drops of pee on your neighbour's toilet
...than to notice the big, stinking pile of shit in yours. =_=
