How do you kill a memory???

I'm not sure you can, however, you can make new, better ones. Pretty soon, you'll forget that one more often.

Memories are like bad horror flicks you think you've killed and and it comes back for a sequel

Drown it in booze so you don't get confused. Sorry, kinda rhymes and I like that.

Stab it with new memories

I wish I knew.

Scotch

Vodka

By not living it and letting it just stay in the subconscious would do. No need to kill.
They are an aid to our transformations and evolution.

You study the memory and change the details of it and you keep on repeating the process until you believe your own lies.

Just don't think of it.

You just don't care about it.

You don't you live with it...
