I think your parents were incredibly strict and that you are an only child (or you had very little in the way of bonding with your siblings). The former lead to you holding onto your shits as a child – i.e. fixated at the anal stage of development. This has carried on into adulthood and turned you into an anally retentive individual. Combine this with the only child aspect and not only are you anally retentive, but you are a wee bit of an attention seeker. Close? I'd reckon it's bang on the money.
Wrong.
But it's not about me.
You are, as I keep saying, a bright fella, but you don't like to show it.
Relax, join in the fun, what's the worst that could happen?
