Eh, you wouldn’t say that if you could see my refrigerator now. I’m outnumbered and outmassed by young adults (severally and in combination).

As long as he's not wanting anyone's head on a platter, you are good to go. Otherwise you'll have to send him to Russia for the rest of his education..
The milk and the bread would last longer though.
