The Poem I Do, Did, Done

What is the future? The present? The past? Just a quick question I thought I'd just ask Can scientists help us? So is it mere physics? Is time metaphysical? Mental Olympics? Do we walk backwards? See only what's been? Or look into the fog? Far future unseen Is there free will? Are we our own author? No, destiny damns us to English tense torture! I write this poem - the tense present simple But simple soon ends with a present participle Continuous tenses use "ing" at the end For perfect (all tenses) add "ed" to amend "Was", "will" and "am" - past, future and present Irregular verbs? Long list most unpleasant Spring sprang and sprung, unique without clone Write, wrote and written I know, knew and known A bit of a burden if not your first language Unless you can master whilst eating a sandwich But if we banned grammar and wrote more carefree Our script becomes blander - we lose poetry (Entry for past, present, future competition originally - recycled for the zany contest)
