In our culture, the act of celebrating is very tied to specific reasons for celebration — birthdays, graduations, marriages and the like. There are certain markers that are universally understood: We eat cake. We dance. We break piñatas. 'But shame-eating a cake in your crib because you’re stressed and lonely is different than eating cake with your best friends because someone had a baby,' Sarah says. 'In that sense, celebration is an energy, an awareness, it is possible at all times and is present wherever there is a human spirit.'
