I Hate Bad Grammar

I am not a grammar Nazi, my grammar is far from perfect nor do I correct people unless I feel as though it will help them or if it's in a playful manor (My ex and I used to have Grammar wars, it was all fun). However, pointless spelling mistakes anger me, I saw a facebook status where a person spelt competition, compitition... I simply don't understand if you have time to post pointless facebook statuses, yet they can't spell the simplest words. I have not and will not correct them because it's harsh and pointless and there may be underlying reasons e.g. dyslexia, stress etc., that makes me incapable of ridiculing others.
