We were in the playground acting out Vending Machine Mum the other day and just getting to the bit where she’s making my bed while I’m completely not helping at all.
This is some in cartoon. I want to comprehend the bold part : Can we replace the bold part with ‘being sorry because‘ ?
No, ‘just getting to the bit’ refers to a particular point in a series of things. You could be baking bread, and just getting to the bit where you’re putting it in the oven. You could be driving a car home and just getting to the bit where you’re turning into your driveway. It doesn’t have anything to do with sorrow, or regrets.
