Grace bought me my first cabinet humidor then was shocked(!) when it filled up.
I wouldn't say she loves the hobby, but she's tremendously supportive of my "guy time". It doesn't hurt that Moe plies her with cannolis.
Very occasionally she'll sit on the deck with me smoking one her flavored cigars. I don't think she actually likes the cigar as much as she enjoys the bonding over a shared moment.
And she's the bestest herf hostess I could ask for.
