Snape's house

Hello everyone – I have really enjoyed reading your thoughts on
the books – it has given me a lot of interesting things to think
about.  This is my first post so I don't know exactly how this will go
down, or if it has been mentioned (or refuted) before, but I had a 
thought when rereading the `Snape's worst memory' scene in OotP. 
Following the world book day chat we know that MWPP were in 
Gryffindor – that's four boys.  If there are five boys per house per 
year (which isn't necessarily true), who is the fifth?

I thought that it may perhaps be Snape, which is possibly why he got 
on James and Sirius' nerves so much and why Snape was apparently
so interested in what they were up to.  Snape may have wanted to get 
into Slytherin (which explains why he is now their Head of House),  
but what if the sorting hat placed him in Gryffindor instead? If this 
is the case, it seems to me that Snape must have had a pretty lonely 
time at school.  The other four boys didn't like him (two hated
him), so he had to hang around on his own, or with a group of older 
Slytherins who spotted his potential, took him in and persuaded him 
to be a death eater – which finally made him feel included.   He 
perhaps deducts so many points from Gryffindor because he had a such 
a rubbish time in the house and wants to get his own back on some 
level.

I know it is a bit far-fetched, but what do you guys think?
