I think you meant "already dropped" not "alredy droped" .... we aren't in the era of annoying to type mobile phones anymore....
Trust me when I say that I am by far a grammar nazi, back when I used to write I had to have an editor fix my work often.... I just hate seeing text that seems to belong back when I was in highschool..... like "h8 2 b rude" etc..... If I was a grammar nazi I would most likely be complaining about the use of "tq" as thanks. however obviously I didn't... I just assumed they made a mistake when writing it and offered a correction since I didn't think it was possible to write in such a manner willingly .... at least I was hoping that wasn't the case... granted I took it a little too far with the comment after said correction but at the time I didn't really think anything of it.
