I am in bed, sick.
The boy has been sick for days, now me.
He doesn't yet understand how these things work, so he will offer to share his food with me. Crackers, sliced fruit, cheese, all of it handled and some of it slobbered on. It all gets shared. It would hurt his feelings not to divide our portions unequally together. We have an understanding about such things.
So, now I lie in bed and suffer, nothing left to share.
