Though I do wish to make it clear that I prefer quality to quantity. Sure, I dislike a single line response because chiefly it makes it difficult to bounce off of, buuut if you want to take the time to be happy with your reply, do feel free. I don't like rushing to make my replies and often do stall to ensure that my reply is to my satisfaction, so I don't mind that/if you do the same!
Equally, your reply doesn't have to match the same length to mine. I might produce a five+ stint of paragraphs, but if you feel you're happy with a paragraph or two in length, then that works for me too. There will be times where you get your writing bug, thrash out five+ paragraphs and I only reply with couple in return... it's tides. I'm happy either way there.
