Hi All

Today, for some strange reason, I got thinking about the ghosts in HP. From 
memory, they are cold to the touch, well not touch, but when they 'interact' 
with a person. I'm sure Harry had that feeling in PS when Sir Nick sat next 
to him. Now, later in the series, I'm sure I remember Myrtle being in the 
bath with Harry (could be a film confusion here though) and he never 
commented about being cold. I also seem to remember Myrtle being in the lake 
too, with again no mention of coldness (that I can remember). This confused 
me! Any thoughts?

The other thought I had was how Sir Nick could be blown out of the way when 
he was petrified. Are ghosts affected by wind?

And lastly, if someone became a ghost, could they ever go back on that 
decision? Or do you think they are tied to that choice for eternity?
