Ok I have seen cases where person a told person b to stop and then person b said well you do it more was this no this isnt the right way to go about something its better to say ok I understand and ease playing the blame game is childish and immature instead its better to acknowledge the other persons feelings and make the appropriate adjustments to do other wise will only piss your pal off making you look like a loser or a jerk or in sensitive towards your pals feelings and thats just cold now we all make mistakes yes but once you make one you must fix it obviously
