person A: I can't believe my husband hid a talent her had from me for 15 years. 
person B: That sounds interesting.. What was it? And how did you find out? And why did he hide it! If you don't mind me asking_comma_ of course...
person A: I happen to come across all his drawings. He is as good as most professional artists! 
person B: Oh I see.. Well that's a pretty positive talent then_comma_ huh? Maybe you should encourage him to keep doing it. Maybe he misses it. You could get him a present for his birthday or Christmas that was related to drawing tools/pencils and all that.
