When I type LOLE 
it is not misspelled because the abbreviation stands for 
'Laugh out loud evily' 
It does not necessarily mean that I was purposely mean or evil but that is how I would DESCRIBE me and my sis's laugh
If the comment has a SIS: or anything similar on my account then that is my sis because we share my account so I told her to type that in case of some misunderstanding like thinking that I am gay or my sis is a lesbian or something, which we are not!
So if the comment is without an indication of my sis then it would be most likely be me. 
My sis has a lot of spare time than me so she always gets the pick and I read what she reads, which is a real bother since not all her book are my type.
I am such a mature and kind brother, I should get an award!
Not that I don't get one, as long as my sis is happy... 
Don't misunderstand
I don't have a sister obsession...
(Is that how you make an emoji?)

Thank you for understanding... :)
