If you're afraid to say "no" then your "yes" means nothing.
"People pleasing" does not come from a desire to be nice.
It comes from fear.
Alcoholism thrives on fear.
Thus, while it appears to be fairly harmless as character defects go, while it seems a little "lite" when it comes to light in the fourth column of an inventory, it is actually very serious business. Alcoholics who are chronic "people pleasers" are moving through life in a constant low-grade state of social anxiety -- of fear -- which both stunts recovery and provides fertile ground for alcoholism to flourish.
