Help I'm trapped in here!

  Oh no! *punches glass*
  Hmm maybe there's a password or something...
  So?

There's a password to set me free! There's a clue to what it is as well. First clue: this password is a sentence, you need the first word. The first word is manners and starts with th. What is the first word?

  This,
  Thankfulness/thankfully,
  Thanks,

Second clue: this word has a ' between 2, the only 2 letters In this word. I AM hoping you figure it out. What is the next word?

  I'm
  A'm
  We're

Last clue: take away the k in a certain word, this word means at the moment.

  Know!
  Now!
  Wow!

Ok now, if you know the real password, there's a few more things out need.

  Ok what are they?
  Ok hurry up
  Meh

You need: kindness, a cupcake, candy, hot cocoa, a big heart, and an imagination.

  Ok I have all those!
  I have some, I have the sweets.
  I have the kind stuff not the sweets.
  I have none of those.

Ok now stir those together and say the password. Then drink the mixture.

  Ok
  Hmm, looks weird but ok
  Yuck no!

I may be free and I may not, if your results say u freed me, good job, if they say I'm still trapped...curse you now I'm gonna die in here!

  O_o
  Ok I hope u didn't die
  Ok

Have a nice day!

  Thanks!
  You too!
  U stink!
