Get the Let Down mug.
When a girl you love decides to leave you dangling on a string over a tank of acid. She promises to love you, then suspends you forever, leaving you to question your sanity while she runs off with someone else. She could help you up, but she would rather keep plucking the string and watch you writhe as you scream in misery.

Why people do this? Because they are all sadists, and they only love to see you suffer, and by the way, your dream doesnt exist. You feel forever empty. You will be Two-face forever.
She was are real Let down. I loved her truly, but she prefered the company of a trailer-trash moron with missing teeth. I write this in tribute to every man who spent years building confidence, only to have it shattered by infectious human waste. You are not forgotten.
