开场百! 苏希收到了一封令她困惑的电子邮件，信中没有句号，也没有大写字母。写信的人在信的结尾没有以正式的“谨启”作结，而是写上“BBFN”，意指“再见”。写信的人是个青少年，青少年写信没必要写成这样写，可是他们就是这么写。
Let＇s begin!Susie got a confusing email. It didn＇t have periods or capital letters. The writer didn＇t end the email in a formalway with ＂Sincerely.＂ Sheended it with ＂BBFN.＂That means ＂Bye-bye for now.＂The writer is a teenager. It＇s not necessary for teens to write like that, but they do.
