My Concern Since I made friends who speak English, Ive had a concern. It's how to reply on chatting. For example, if my friend says, "I went to Tokyo and bought lots of things!" I always just say "That's cool!!!" One more example, if my friend says, "I met a famous comedian!" and i always say, "wow reallyyyyyyyyyyyy?" "cool!" "awesome" "Really" "Wow" "OMG" "Great" Those words are very useful to reply. But when i use those words to reply, I feel bad. I feel I cannot reply well. I wanna say more words, but i can't! I can say some if it's in Japanese, but i don't know why , when i speak in English, i cant do it. so sometimes, i use consonants and vowels continuously, like "wooooooooooow" and "reallyyyyyyyyyyyyyyyyyy", to show my reaction well. but i still feel bad. It is like a robot. I am a robot. If you have any ideas or tell me good response words, I am very glad to know that. And hope someone correct my english! Thanks!
