Yes: iff^[1] u (sic) are actually using an SMS telephone, then please accept my apologies - that would justify the contractions of "you" to "u", etc.


and writing "u", "plz", "tht", etc is pure laziness - if typing "you", "please", "that", etc is too much effort for you, then I can't be bothered to make the effort to look up the precise names in the code library for you.
(not that looking up the precise names in the code library should be so hard any way...)


[1] "iff" = "if and only if"
