  • I hated this stuff in high-school back in the 1980s. Nearly failed the class. This never made sense to me nor could I see the relevance to my life both then and now. Now I'm a successful musician -- I've never used this stuff in my life! LOL

  • @fhood Well, ok. Lot's of people will use it though...like the people who make just about everything you consume everyday...like you guitar strings! See...we're needed too...Just like I need music everyday!

  • @bannanaiscool I agree with you 100%. So my chemistry class should've been an elective course and NOT required. It was required.

  • @fhood Absolutely, chemistry should have been an elective! I agree with you 100%, too!

  • HAHA! My teacher makes it sound so complicated. Thank you so much!

  • No joke man!

    I can understand this better than my teacher, too!

    geeze...my teacher goes way too fast.

    I probably shouldn't have skipped regular chem though...

    but, I can handle it.

    thanks again
