For as long as I can remember, my mom has used stuff similar to theseand let me just say this – as a kid, she used to scare the crap out of me. It's be late at night, I'd need to ask her a question, and so I'd walk in her room and slide up beside the bed. She'd usually be reading a book, so I couldn't see her face, but when she's hear me walk in and start talking she would slowly lower the book. And that's when I wouldn't see my mom, but instead would see some alien impostor with a dark green slimy face and totally freak out. She'd then laugh and call out to me as I ran down the hallway back to my bedroom.
And you know what? I so can't wait to have kids of my own now 😈
