Who cares

Was I that dumb? I might have been happy with you in a past, but why would that mean that I really needed you just so I could keep being that happy? Things change, brake, turn into dust in the end, but doesn't mean you can't live without them anymore. That peace of cake might have fed you for a while, and it was delicious, but does it mean that was the only cake that could make you feel that way until the time you die?
