How to tell a story (past perfect is annoying but necessary)

A man working for the London Ambulance Service was called for help a very old pensioner who had fallen down the stairs. Just go through this short story (with happy ending) and notice only one thing – the using of PAST PERFECT.
I guess this story could have its place in every grammar book.

The patient was a ninety-five year old man, he had needed to change a lightbulb on his upstairs landing. He had gotten a stepladder, climbed up it and in the process of undoing the bulb had toppled backwards. He'd fallen, cracking his head on the lintel of the bathroom door and then he'd rolled down his stairway. When we arrived he had picked himself up and was sitting on the downstairs sofa. His concerned neighbours (who were the ones that called us) had already changed the lightbulb for him. A quick examination showed exactly two injuries. He had a small bleeding wound on his arm and he also had a bump on the back of his head. He hadn't hurt his neck, he hadn't been knocked out, he hadn't broken any of his frail looking bones. He was also a very nice chap.

Pacient byl pětadevadesátiletý starý muž, potřeboval vyměnit žárovku na horním odpočívadle. Měl schůdky, vyšplhal na ně a během odšroubovávání té žárovky se svalil dozadu. Sletěl, narazil si hlavou o futro koupelnových dveří a pak se kutálel po schodišti. Když jsme dorazili (tedy – před tím, než jsme dorazili), on se sám zvedl a seděl na válendě v přízemí. Jeho starostlivý soused (který byl jediný, co nás zavolal) muj už žárovku vyměnil. Rychlá prohlídka ukázala přesně dvě zranění. Měl malou krvácející ránu na paži a taky měl bouli vzadu na hlavě. Nezranil si krk, nebyl omráčený, nezlomil si žádnou ze svých křehce vypadajících kostí. Byl to taky velmi milý zákazník.

Just in case:
PAST PERFECT refers to a time earlier than before now. It is used to make it clear that one event happened before another in the past. It does not matter which event is mentioned first - the tense makes it clear which one happened first. In other words: The past perfect is used to show you which of two events happened first.

The way of using past perfect is HAD + PAST PARTICIPLE (3. tvar slovesa)

The train had just left when I arrived at the station.
It was obvious that something had happened to them.
I had planned to read this book but just didn't have time.
