We've been very lonely, but we had it easy. Because death is so heavy - we, too young to know about it, couldn't handle it. After this you and I may end up seeing nothing but suffering, difficulty and ugliness, but if only you'll agree to it, I want for us to go on to more difficult places, happier places, what ever comes, together. I want you to make the decision after you're completely better, so take your time thinking about it. In the mean time, though, don't disappear on me.
