Hi viking_metal, technically you have a sonnet , the only one absolute rule about a sonnet is the fourteen lines. I know this may start an argument, but all I know is what I see on Jeopardy.
The third stanza is it speaking of the child or the wall ? Of course its the child walls donít talk. I was thinking of the clichť ~ If those walls could only talk~
I donít guess I helped much, I never do, but at least you know you wrote a sonnet.
