Sometimes I wish Echo never moved into my mind. She's really quite annoying.

Before:

I have come to a conclusion that since Echo can read my mind, I just need to think of what I want to say to her. I have a feeling Echo was waiting for me to think of this for a while. I also have a feeling that she is being amused by my thoughts right now.

Quite right.

I feel very triumphant that she has not called me "child" all today.

...

Right now I do not feel so triumphant. I feel dumb that I thought that into words.

You should, child. Now I know why the house-dwelling boggarts have so much fun. After this I think I shall have tea with Dil.

Who's Dil? What's a boggart? Why are you SO CONFUSING? I think I have the right to freak out that a "spirit" is in my mind.
First of all, Dil is a house boggart. A house boggart is a mischievous shape-shifter that lives solely for mischief and tricks and laughs. When they aren't in another form they are invisible, and they are bound by the Old Laws to never talk to humans. And I'm not confusing. ... And what of your morals?
She was right. My morals... hmm. Well, I hated being forced to do anything. I hate being trapped. I hated how misery could take over your life so easily. So, I live by this rule: no matter what happens to you, live with it. Don't freak out. Don't cry. Don't shout. Live life as if nothing has happened. Move on. Don't let anyone see. Stay unnoticed. Hidden. Safe. ... Sometimes I really hated how she seemed to know everything about me.
Child, I do know everything about you. I've spent centuries memorizing everything about you.
I was very bewildered when I heard that.
How is that possible?
Well...
And with that she sent me spiraling towards memory lane.
--------
And that is how I saw her memory of her first sight of me.
