Don't take my concern as a joke.

Yup. As my title has already said....

I was concerned for that someone, I texted that someone, I looked out for that someone. There was no respond from that someone. Made me really worried.

After a day then I realised, that someone is okay and that someone just didn't want to reply me, that's all.

Walked up to me giving a sacarstic question to me, was the last thing I wanted to hear.

My concern was sincere, not meant for that someone as a joke.

To hell with you.
