Is it only autists that have collections

My step dad, who is NT has collection of watches, he used to collect other stuff too in the past. As for me - I used to collect my own works. I had a big collection of my own tram line schemes, with whole infrastructure and timetables, then I drew house plans, there were also little paper dolls (around 10 cm tall) - these were my collections from childhood and adolescence. I used to dir hours and do these things. There were also whole notebooks filled with all sorts of data that I myself created I don’t understand for what other than for some sort of pleasure although I often was tired of doing it (EAN codes and names of products, names, telephone numbers and addresses, passport photos - portraits that I drew) etc. I come from poor family so I had no possibility to collect stuff that you can buy. But I also had a collection of stones found in the street or park. Ah and collections of photos of trams - forms cards, newspapers etc. I loved to also find some information about them and write which model, year of production and any other data that I could find.
