<human>: I'll start
When I was smaller (around 7 or 8. Maybe way off. I don't actually recall my age. At all) My sister was having her room redecorated or something. I spotted one of her posters on an armchair in the corner of the loungeroom, face down. I was a curious child. So I went over and investigated. Being alone in the room, I thought I would try something. I looked at my surroundings and made sure no one was there whatsoever, peeled the blu-tac off the back of the poster and stuck it riiiight up my nose. Then pulled it back out again. I found it quite amusing, so I did it again, and again, and again.

It gets better.

It got stuck and I freaked out so much. I had a mild panic attack and decided not to speak a word to anyone out of embaressment. I kept my word to myself. A couple of years later, after falling ill many times with infections, mum decided on getting my tonsils removed Everyone (even my GP) thought it was an issue regarding my tonsils So, we went on with the procedure. I didn't even know what was happening, infact I think I forgot all about the blu-tac by then. I erased it from my memory or I may have thought it fell out in my sleep or something. 

Nope. Not the case

As I was having surgery done, AFTER the removing of my tonsils they cleaned out my nasal passage and sinus', and out popped a piece of blu-tac, so I'm told. I woke up from surgery and they showed me a little urine cup with a dirty piece of what appeared to be a giant booger. After a quick observation I realised what it was. Blu-Tac

Can you give me a shortened version of the text?
<bot>: Underwent surgery as a small child just cause I didn't want to go through embarrassment and didn't even know about it
