What a wonderful thing to feel nothing at all. Then, there is nothing to lose. There is no emotional garden to tend, therefore, no need to water the flowers, because it will not matter if they die.
i wrote this millenniums ago lol but basically if you don't get it, its a metaphor. I was comparing emotions to a garden(although they have nothing in common), blah blah blah, if you don't have feelings then you can't get hurt, therefore you have nothing to lose, blah blah blah, therefore in your metaphorical garden, because you have nothing to lose, when the flowers die it doesn't matter, as compared to if you had feelings, you would have to constantly repair and tend your garden(feelings) if they got damaged or whatever to keep your garden(feelings/you) stable, don't think about it too much.
