There's a way.

We had an English workshop today; I was so excited to see my friends. It's been a while since I last spoke with an English native speaker. In no time after attending the workshop, oh, my, I found my English a little bit rusty.
During our children's spring break, my friends and I tried to find some time to study English together; however, it seems to me that there was a slight difference between chatting with Japanese friends and speaking to native speakers --- even if we spoke only English. During today's workshop, I sometimes had to give up expressing my thoughts clearly because of my miserably poor vocabularies.
Well, well, well. I must admit that I need to practice speaking more.
