Metrical Breaks and Line Variations

1)
I know that school should be some fun
But I don't see that side of it
I only know of work and strife
Mom and Dad are kidding themselves

2)
"What do you want to be when you grow up?"
I hear this all the time,
"Why do I need to have answers right now?"
I want to say just that,
Knowing my parents would want me to say
I know exactly what.

The first poem has three lines of iambic tetrameter followed by a line of trochaic tetrameter. This poem expresses my exaspiration with Mom and Dad for thinking that school is fun all the time and the last line is emphasized to plainly tell the reader what I think about Mom and Dad's attitude.
The second poem has alternating lines of dactylic trimeter with an extra stressed syllable on the end and iambic trimeter. This is also a form of venting for me, because since I'm getting ready for college, people ask me what I want to do when I grow up and/or what I want to major in. It gets rather tiring, and Mom and Dad seem to think I should already have an exact idea. I guess I don't handle getting older very well.
