How to deal with toxic seniors in residency?
Don’t give them a fuck… everyone learns in 3 years residency …not a great role of seniors…
Just focus on peaceful learning and study and get passed…
Be more toxic… give taste of their own medicine 
Thank me later
Just ask them how to deal with you in a simple way.
