Is there a special memory you remember that you just can't stop forget?
I myself have plenty.
When I was lvl 14-20 (first character) I went to Orgrimmar and begged people for some money since I had repairs to do and had only coppers, Then I got like 1 gold/5 gold/20 gold and I felt like I was one of the richest ingame.
Like when I looted Swift Zulian Tiger after MANY tries.
I was the type of person who didn't raid but to explore and find new stuff until WotLK where my very first raid was Naxxramas. It was so awesome to see these big monsters playing with IRL and guildies.
Idk, I am just happy when i remember these.
