This may sound a bit random but I have realsied I make assumptions about people based on their usernames! FIONA is the one I was thinking of in particular because I always imagien her to be shouting and people that shout scare me slightly so I am nervous about reading her posts (sorry FIONA I am slightly mental!)
AlmostMrsP automatically makes me smile because on BT people occasionally refer to me as MrsP so when I see ehr username I think bless shes nearly like mt he poor sod!
crafty em makes me think of crafty as in has a glint in her eye like some sort of Artful Dodger.
RaeF sounds like it Ralph said the posh way and makes me think of that actor I like and imagine her to be charming like him.
I'll stop now before I embarrass myself anymore.
