whenever i find myself in these situations i remind myself that we are all subject to the same cycles of suffering, the same grasping and the same resistance to change. i can recall many times where i have been an annoyance or a negative person and it's usually due to an internal problem that i'm dealing with. i like to give people the benefit of the doubt and remember that their behavior is likely a result of their own suffering.... always reminding myself that the negativity of others is not mine to carry. i think that the western way of thinking (huge emphasis on self-centeredness, individuality, seeking for power) allows us to slip into this headspace, where you are upset with others for not doing things the way you would or simply doing things that disrupt our own activities, very easily. it's not necessarily your fault but more so how we've been conditioned... practicing compassion seems easy in theory but can be very hard in practice sometimes. providing yourself with gentle reminders about the truths of our silly little existence is the best way to counteract the irritation you feel at times. remind yourself that we are just little animals and that these feelings are just weather and it will pass.
