Could I write a friendship poem?

I wonder if I could write a good poem about friendship. I wonder what it would take for me to do so.

I think the best poetry I've ever written is probably the two sonnets I wrote for my Renaissance Literature class at UBC; I've always been a bit shy about showing them to the world because, well, they're somewhat extravagant expressions of romantic love, which is just not a thing I do. (I think it's kind of funny that the only time I've ever written love poetry was when I wasn't in love. :-)

When I wrote them, I think it was important that I read a lot of sonnets by the authors we were studying, way beyond what was required for class. I think steeping myself in the poetry I was imitating was important for me to be able to write something in the same metre and at least a similar style.

I also think that I've really only been successful at writing bits of alliterative verse in Modern English when I've been reading Old English alliterative verse.

That suggests that to write in a particular style and metre, I might need to be reading that style and metre.

I have no idea what style or metre I'd want to write a poem about friendship in.
