Ooh AF you must have been her favourite then 
It's very rare anyone talks to me either MrsW but I bumble around popping in and out of threads anyway. I think I'm just a natural potterer!
I have to be honest though if anything ever disproved the words on a screen analogy it's this.
They're words, plain and simple. Words are the same whether spoken or written. Real words said to real people. Regardless of whether people are who they appear to be they are still people. Words are the most powerful thing in the world.
Of course 75% of what's said on here and in RL is pointless waffle, that's the basis of most conversations isn't it? Fluff and nonsense.
But words can hurt, hurt like nothing else. They can also lift you when you think nothing can. Words matter.
