Yup! And “injected intravenously” could actually be done one of two ways: with commas (incorrectly done here) or with en- or em-dashes. For example, “the substance that – injected intravenously – turns women into cats!” (en-dashes) or “the substance that—injected intravenously—turns women into cats!” (em-dashes) are both valid. I often tend to prefer en-dashes because I think they’re easier to read than em-dashes and put more emphasis than commas on the idea that this is a bit of an aside. I think commas are just a bit too overloaded and that en-dashes add more flexibility to grammar.
Misery, misery, misery, that’s what you’ve chosen. I offered to read an email, and you spat in my face.
