- I print emails, when they contain some information I will need while say driving somewhere.

- I use colors which help with Question / Answer situations.

- I use single letter sign offs when on a cellphone responding.

- I use some txt speach when on a cellphone, not too crazy because sometimes thinking of a clever abbreviation is more painful than just writing the damn word out, also autocomplete helps. I also explicitly tell people that "u" is ok or "ur" or "k" or something in that nature, but things I can't figure out within 20 seconds are not.

So yea, reply to shitty txt speach "I dont get it, please say again without abbreviations" it annoys because they have to send it twice.

Reply to a shitty colored email with a massively colored one.

Single letter signoffs... wait what bothers you about this?
