Sometimes when I read my answers and comments from the past, they make no sense whatsoever...

Also if i make a comment on your question, I am only giving my 2 cents (no paper, no pen) $-$ just my initial thought, so if i am too off don't be alarmed.

Update: I don't get on this site as much as I used to, so I sometimes just lurk around seeing if I can answer something without typing too much
