I know what's you are talking about. I couldn't contact you because I was busy with my work. I feel a little awkward that the situation is like I didn't contact you because I had bad feelings, while actually there is no such reason.
Anyway, what you are saying is a sure thing, and I was also thinking like that.
I'll return your cellphone within few days. I'm sorry.
I should have given it back to you before you asked me..
