my homestay mom ホストマザーについて

I started to be get used to talking with My host mother. But l often can’t understand  what she says , so l am worried about University life. I really want to join a club. I guess a lot of Japanese students start to study at UCR at the same time and most of them are gonna join SAKURA-BU. But l want to interact with people from other countries so l wonder if l join the club even though l’ve decided to join the club before coming here.Anyway my mom picks us up whenever we want, so l am happy because l can join any club. She also gives us a bottle of water everyday to save our money. She also said “optional trip is too expensive so l gonna take you  to shopping moll or somewhere we want to go.How kind she is!
