A few weeks ago, I called one of my friend. We haven't seen each other for a long time. When I asked him how he was doing, he said he was in a very good mood. Then, after a couple of minute he told me he had a tumor on his brain O__O He didnt seem to be too worried about it because he wasnt afraid of death. We talked for a little while. My friend told me he would call me again someday.

I'm worried because we never talked since the last time I called him. I'm wondering if I should call him because I don't know if he's okay
