It's around a week ago he suddenly came into my lab after I never met him for couple of months. I'm little bit surprise and happy for seeing him again. As usual, me turn out noisy if met someone who I already know, I asked him from how thing was, what he doing now, why he took a break and so on. Later I know that he's studying English now. Then, at the middle of conversation he unexpectedly told something;
Just ignore and don't think about it, please!
