I've mentioned a few times my therapist uses a mirror as a metaphor for staying in and owning my reality. I've been saying for the last year that nothing is personal and everything everyone says and does is a reflection of their own reality.
With that thought in mind and because I just now learned this little trick... I took each instance where the other person said 'you' and replaced it with 'I' or 'me':
I'm (you're) too selfish and don't give a sheet about anyone else but me (you).
The flip side is that it applies to me and my words as well
