I don't know why i don't know why i'm so stressed to chat with foreigners,It makes me excited but i think i paid too much attention on my grammer mistakes,my words and some other things and i neglected some funny and intreresting things.And i also think that it's harder that i talk to some native speskers than i communicating with chinese people in english.I was dying to change the situation but i didn't find a way.I hope we can made some progress together with my pen-pal !
