Understand the feeling...there is very superficial interest on plants, friends do admire them..but once you start telling them how to properly grow them, their eyes glaze over, you feel the panic in their thoughts and slowly they drift away from talking about it. So I have learned to just smile and wait a little more to hear more sensible questions, before I embark talking about them. Lessens my frustration, besides, everyone has their own passion to cater to. Live and let live.
