It turned out that wizards like Ron, Hermione, who are Harry's best friends, are everywhere throuout the world, not just in UK.
Though Harry is a bit different from other wizards because of the fact that he is the only one who survived the attack of Voldemort, which killed Harry's parents and made Harry live with his only relatives, Uncle Vernon, Aunt Petunia, and their kid Dudley, who are very mean to Harry because they dislike wizards or magic.
This time Harry went to the Quidditch World Cup with Ron, Hermione and Ron's family.
Just so you know, Ron's older brothers George and Fred are so funny, and Ron's baby sister Ginny is so cute.
George and Fred are twin and play a lot of practical jokes, so that their mother often scolds them.
Ginny is the only girl in the Ron's family and likes Harry a lot so she used to blushed at meeting Harry.
I'll tell you when I finish reading.
