im not a fan of negative behavior at the table so i agree with your views.
we all have certain thresholds for pain and what we can handle, this is truly tested at the poker table.
its all a matter of time, how long will it take him to realize that tilting is bad for his growth as a player. The same thing i mentioned to you the other day about learning to control tilt
good game though! nice to see you holding your own at the tables. keep it up
