Ha, Juggling ... well the biscuits are easy. They're one of the things I gave up for Lent so I was counting down the hours until midnight hit and it was Sunday so I could stuff a whole week's worth down my gullet. So refined 
As for confession, not nosy at all, I'm always interested in how other Christians live ...
it would be fairly common to describe it as a 'good confession' if it has been the occasion of a genuine examination of one's life, repentance and conversion (as opposed to just going through the motions and reciting the same tired old list of sins that I do every other time, which can also happen), and also if the priest was helpful/understanding/gave good advice.
In terms of what we confess, obviously people sometimes have 'big ticket' blatant sins (adultery, perjury, drowning kittens ...), but apart from those, we prepare by reading Scripture, maybe use a printed examination of conscience (which has a whole list of 'Have I done x sin?') and make a note of what comes to mind (I personally don't use a pre-prepared examination of conscience, but they are very common). So, for example: impatience with the dc, lack of consideration for dh, uncharitable thoughts about a colleague, judgemental attitude towards someone at church, gossiping, wasting time at work, neglecting prayer life, refusal to help someone in need, holding a grudge, being overly concerned about a material possession, failing to trust in God's providence (in a particular situation) ... Not all of those would be sins in every situation, there needs to have been a certain degree of having deliberately chosen that course of action rather than acting unconciously/forgetting.
It sounds a bit negative when I put it like that, but actually it's a really positive and uplifting experience. Being able to admit all the ways I say no to God in my life and face up to who I am (which includes an acknowledgement of the good that God has worked in me), receive the overflowing superabundance of his mercy and move on, cleansed and renewed and reborn. I love confession!
