The task is to find the longest intelligible and grammatical English sentence containing only words of two or fewer letters.
To limit the possibilities, you may use only the following words:
Single letter words, "I" (pronoun), "A" or "a" (indefinite article)
Two letter words listed here https://www.lexico.com/explore/two-letter-words
Punctuation is allowed as long as it doesn't end the sentence prematurely.
This is a competition. I hope that's allowed. I'll start by introducing myself (or at least my gender).
I am a he, Hi!
