Do you need a vase? Science says yes. (Junk science anyway, the kind we have all become accustomed to.) But really, buy a vase. Look at it. Sometimes put flowers in it. It will be yours and then when you are old, you can have a feeling about it. Some stuff is good to have. If you grow tired of it, put it in a storage unit for a few years and then when you bring it out, you will embrace life again.
