For whatever reason, I grew up thinking that buying flowers was self-indulgent and wasteful. It was only appropriate if someone died, and slightly suspect even then.
As an adult, I am ridiculously pro-flower. I buy flowers with nearly every grocery trip. I usually don't spent much, and having them around improves my quality of life to an extent I would never have expected. So that's my Happy Housewife thought today--no matter what else you have going on, if you can swing it, buy yourself some flowers.
Mine are peonies.
