I don't think any line stands out to me, which is not to say that none of them were good enough, but rather it was so consistently funny throughout that I can't choose! You craft every sentence with care, striking a deeply unique and individual tone, and I was laughing throughout at the perennial woe that made up your day. I was also, incidentally, astonished about how you managed to get through the whole piece without repeating yourself - it was like you were constantly generating new ways to express disbelief and astonishment in comical ways. With some tweaking in the suggested areas re wording, and the occasional correction of language that could be read as a tad too informal, this would be perfectly sustained.
As I've already said, this was deeply enjoyable for me to read. It reads almost like a comic monologue, intended to have an audience on the floor laughing. You struck the perfect balance in terms of wit, making it seem effortless and conversational but including also an element of similarity to stand-up comedy. However, I do think that the residual feeling after one finishes the piece could be improved by development on the final events. After all, this (the bus saga) is surely as significant on the timeline as the stomach ache - could it get as much screen time, so to speak? Could it be fleshed out a tad to add to the comedy, rather than just stated plainly as an event? It feels as though you became slightly rushed at the end, and it didn't balance that well with the start, when you were giving insignificant lessons full paragraphs.
Is this autobiographical? I love the idea of you crafting this work as you recover from a long day of stress. It made for a very effective ending, bringing us up to the present day.
I would love to see this staged - it seems written to be spoken, not to be read. I can imagine how much more comic effect could be added with a few timely pauses, the odd sigh and, most importantly, facial expressions! I would love to see how you'd do this on the stage - perhaps with a narrator and people physically showing the action, or just a monologue. Although of course it reads well, you could add whole new dimensions if you were to have it physically read out and/or demonstrated to an audience.
Overall, really well done for this - I loved reading it (it improved my day, if that's any consolation) and it seems like you've had a lot of fun with it too. I look forward to reading more of your work in future (and I won't be able to miss your distinctive tone!).
