I'm thinking of selling my son's taxidermy collection?
How old is your son? Have you discussed it with him?
He is 15 years old, no I haven't discussed it with him. I might wait till he turns 18.
If he doesn't know then you shouldn't decide if you sell it for him. He would be upset since he has spent a long time on that hobby.
I think it's a strange hobby he needs to outgrow. He's being weird and he is not able to face reality.
How is he not able to face reality? I think you are being too harsh on him. As a parent you should be more supportive.
