I'm just left with dead bits

Aw man, I'm no good at plants!

Why what have you done?

Snapped the only bit that was alive off. Now it's just dead bits. Aggr I can't do plants. I'm bad at plants.

You're missing something

What? That I'm really shit at plants

No, that sentence is missing something 

That I didn't get taught plants because my mum is shit and kills plants too?

No, like a doing word

OK, I'm shit at doing plants

No, like a noun or a verb, which one means a doing word?

I don't know, I think I missed that day at school. Like I either wasn't there, or probably was just thinking about something else

Me too

You'll have to ask our son. He knows everything.

Yeah, he does school

Maybe if I just put this bit in there it will grow back

Yeah, maybe
