When I was a child ( about a year ago , now I am a mature and grown man already) I found a book without a cover in the very old house in mountains, where we were staying on summer vacanction.

You were a child last year, and this year you are a mature man?

In English we normally talk about children then teenagers then adults seperately. So children are <13, teenagers are 13-19, and adults are 18+ (or 20+, or 21+... depends a little on local culture). So normally there would be at least a 5 year gap between being described as a child and being described as an adult.

Or perhaps you meant "some years ago" rather than "about a year ago"?

I started reading it and spent several wonderful evenings with this book, reading in bed before sleeping.

One day he was hosting a passing by group of older guys passing through ( some of them were withhad beards already) from a neighbouring country.

"passing by" is like a momentary interaction, like passing someone on the street in a couple of minutes. If they stayed long enough to be hosted, then "passing through" is more natural.

"neighbouring" is the adjective of "neighbour"

These older guys wanted to mtake a trip to an exotic place with a big sacred mountain and have some fun on the way, combining business and pleasure.

So this young guy decided to go with them .

They have had a lot of interesting adventures and a lot of fun.

I could not understand why they were traveling for several months ( almost a year actually).

Don't they have a work to do ?

The young guy's age hwas been mentioned assaid to be 50 which is definitely a mistake.

Anyway it was a veruy nice story and I liked it very much.

I wish this story will beas taught in school instead of math.
