Lol, just tell her they brighten up your day! And that's all that matters right? When I wake up to see one of my orchids bloom, it makes my entire day that much happier!
I mostly leave my spikes on, until they brown... But depending on the plant, sometimes I won't let them reflower if it's detrimental to their health (like for the NOID's from big box stores, when I get them home, but, I don't have too many of those). Most of my orchids, are species Phals, so they have green spikes that rebloom year-after-year.
