Erin and her Diary-ah

Ethan and I were talking about my blog (this blog) when Erin overheard us and interjected.
Erin: What's a blog?
Me: It's like a website
Erin: What's a website?
Me: Well, it's more like a journal
Erin: What's a journal?
Me: Like a diary
Erin: What's a diary. I only know diarrhea.

Well, yeah, that's what this is.
