Hello Lilly-san!
No problem! you are not crazy! I am honoured of that (being your first japanese friend!) I am a Happy-go-lucky type of girl, I looooove to tease my friends (Not in the wrong way of course) one day, my 先輩 or 'Senpai' In romaji (If you don't understand Is a person with more experience in a field, she's one year older than me) Lisa tried to embarrass me in front of my crush and then i did the same, do you think that is good?! now my crush thinks that i'm crazy!!
bye!
Hikari :3
