I will never understand. I admit lately i have been so disconnected. I agree with Amanda below, sometimes i enjoy the article yet have nothing to add and will leave a generic comment, yet then if i read one that i have stuff to say i leave a longer comment. yet lately i have been reading a lot of random stuff and just not commenting. But sometimes i do that because i am reading, i have read a bunch of stories of people i love and not comment then go back to the story when i have something to add reread and comment.
That happens a lot lately to me, not sure why. Prob cuz my mind is in the clouds lately.
