I will always be you

Steal my prefix and I am you.

Steal my suffix and I am you.

Steal my infix and I am you.

Are you a MEME

Steal my prefix and I am you.

Meme - me is me.

Steal my suffix and I am you.

Meme - me is me

Steal my infix and I am you.

Meme - em is me

• First of all, clever! Second of all, I think I'm missing something. How is "em" me? 'Em can mean "them," but that's neither "me" nor "you" (since it's not referring either to the speaker or the person being spoken to), is it? Or maybe "em" has a meaning I don't know? Jan 27 '21 at 17:35
• I assume it's "meme minus me". I.e. remove the infix em from meme and get me. Jan 28 '21 at 6:57

Smartest1here's answer uses the fact that each "you" refers to the same person.
Instead, it could be that each "you" refers to a different set of people.
