Don't let go of something you cannot bear to be seen held by others.
Don't hold on to something you know you will let go.
Don't hold on to something when you know it is already held by someone else.
Do not hold on to something when you already are holding someone else's hand.
It's really hard letting go of something you've held on to dearly for the last few years. You know what's harder though? Realizing that all the timey you were holding his hand, someone else was holding on the other one. Now that my dear, is the real sad story.
