What colour was your first bike?
k now, which way did you look?
I've seen people look diagonals sometimes... not sure if there are combinations... actually I'm not sure how legit this is, I heard of it from a friend on the bus who works in education
Oh, and if that question wasn't fitting, just recall your childhood or something sometime and try not to bias it, it's pretty hard to do, but you know...
edit: oh and logical=> your trigger for your memories is a logical connection
emotional=> your trigger for memories is an emotional connection --- that's mine
musical=> trigger for memories is a musical/rhythmic one.
