Poetry help! i'm really stuck Options

[mikazukix]

I have to write a poem reflecting on my grandma or my memories of her for her birthday event thing. I know it's kinda of a personal thing but she's just like any grandma kind and friendly, loving u know te usual.Anyways my job is to make a poem. It's kind of a formal thing so it can't be humourous.( well i don;t think it'll be very good if it was) I going to try to go with a rhyming scheme. Also.. i want to it sound professional but not too professional but then again i don't want it to sound like a little kid could write sumthing way better than me. The first line is the most important right? So i've been like stuck thinking for one.. that isn't so sappy or just weird. So.. can anyone help me out to what the first line might be? or maybe give me ideas of what it should be like ?
The best thing i can think of is something like "as time goes byI still remember all the times we've shared together" Bad right? It sounds kinda sappy. I've been stuck on this for like a month. seriously.. i wrote a couple poems but they all really really.. really.. suck. HOPe u can help out. I don't even know if anyone in createblog is into poetry. >.<

Here's 1 of my poemsthat aren't very good

Congradulations on ur special day
Through the years you did portray your gift for cooking
your orderly nature
your faith in god
and your kind behavior
It is these points and many more,
that make you grand
for all to adore
So when yur down
with nothing to bare
Your friends and family are the ones
that care.

Yeah...... plus it'skinda short. I was actually thinking with starting with a metaphor or sumthing but.... i couldn't think of how to or what to compare her to. with out it sounding kinda weird. It has to be obvious cause my grandma doesn't really got those if thier deep metaphors. I thought that maybe a aabb scheme would be okay, or maybe a abab or a abcb. I was just worried that if i don;t stick to a rhyme scheme it might just sound like a speech.
