Unfortunately that is how most human minds work.This kind of sums up how Ukraine is starting to think.....as in NATO owes them and they (NATO) had better hop to and get the equipment, arms and ammo to them right away with zero thank you from Ukraine..
Life is not a credit card, where getting stuff runs up a bill which needs to be repaid.
Probably one of the most difficult lessons of life, is to never expect anything back, when you give to someone.
