A Lesson in Pernunciation

I am always so perplexed when people pronounce words incorrectly. I understand that if you read a word off of a page then you might say it wrong, especially if you've never heard the word before. But there are certain words that are part of our common vinacular and yet people still say them wrong. It's like they're refusing to hear the way every other person on earth says these words. LALALALA, I CAN'T HEAR YOU SAYING THINGS CORRECTLY! I WILL SAY THINGS HOW I WANT TO! NO MATTER WHAT! LALALOODYLOO!

Here are a few words that are currently bothering me:

Massage: muh-sahzh, not muh-sa-jah.

Height: hahyt not hahythe. There is no TH. Where are you pulling that th sound out of??

Spa: Spa not Spal. Ok. this is something I've only heard one person say but she says it every day and it drives me crazy because...spal? I guess refer to above but instead of wondering where the TH came from, wonder where the L came from. But really wonder. I understand how you can be a little dyslexic with the "ht" in height...but Spal?

Pillow: pil-oh not Pell-oh

Also, names. Some names can be pronounced in a variety of ways. However, if someone introduces you in a certain way, that is what you call them. When this person is in your class and you hear people call her name all day long, you hear people say "Hey, And-ree-ah" all day long, you do not have the right to continually refer to her as "On-dray-uh".

And now for the true debate:
"koo-pon" or "kyoo-pon"
According to dictionary.com, either way is acceptable. I'm a koo-pon girl. What about you?
