Is it normal for my brother to pile his pubes in my sink?

Tell him to stop or you’ll tell your parents. He’s harassing you,

Is this your sink as in, your own personal sink? So he shouldn't be using it, and knows that it will be you that finds these pubes?

If this is the case, you need to tell your parents. This sounds like the start of something unpleasant.

That's gross.

Since you said it's your sink, I'm assuming you own the home and he lives in it? Kick his ass out.

This is funny as hell. Lmao!

You can make a black person wig from it

This is hilarious!! How big is the pile? Why does he do that?

Not normal but hilarious

Can you explain what you mean by pile? like he plucked them and put them in a pile? He shaved his pubes in your sink and left trimmings there?

Make jewellery out of it

Hell no.

Wash it away.
