The very best thing in existence is the letter E. It cures all diseases, it saves all lives, it gives all of the poor money so they can have a good life, It will never give you up, it will never say goodbye, it will never let you down, it will never tell a lie and hurt you, it will never make you cry, and it will never run around and desert you.
βYouβre the letter E.β
"E" is used when there is no response you can think of.
"The weather is nice today."
"Yea, it is."
*awkward silence*
"E"
