I'd cheer for all his achievements and comfort him in failure. I'd wipe his tears when he's sad and smile with him when he's happy. I'd be there for him always, because his presence would bring me such bliss, nothing would be enough to pay him back.
I'd snuggle with him every night before bedtime. I'd pet him and kiss his forehead while telling him he lights up my world. And I'd dream of him like everynight, except that this time instead of waking up to screams, I'd wake up to him by my side. And we'd never part ways.
