It's the thought that counts. Use it like a trophy and put it on display.
If you're comfortable with asking him the price, you should be comfortable explaining why you would rather not smoke it.
How old is this young man?
If he can purchase a pipe, he probably can research them a little.
Probably saw it on the counter at the convenience store? "Hey!" "THAT'S what I'll get Dad."
My brother made me a pipe. I'd lured him into the attempt and when he came to visit at a family gathering I'd brought it along to show the rest of the clan.
He looked it over, and seemed surprised that it remained unsmoked.
I told him, well, it really isn't well made as a pipe and to smoke it might work, but to clean it would be easier to make a new pipe. NO, I didn't say that.
I did say that it seemed to have a less than functional drilling.
He seemed a bit miffed, but I'm not sure if it's because I didn't smoke it, or my 'critique'.
He's coming again this weekend. Who knows? He may have gone home and read and watched all the crap I sent him to entreaty him into the craft, and show up with some fine examples of his development?
Honesty is the best policy, if it isn't used as a cudgel. I mean, sheesh, we all have feelings, most of us.
