Ochtfochlach poetry form

Ochtfochlach poems consist of eight lines with a consistent length and meter chosen by the poet. The rhyme scheme is AAAB CCCB. I want to write a poem using this form, but I cannot think of a subject or theme. Sometimes using a specific form is easy and sometime difficult. Right now, I am finding it difficult. I am going to the laundromat tomorrow; perhaps I can come up with something there.
