here's an insight into how my brain works...
i may seem like a flexible person, but really i am not.
once i have made a decision, when i have to change it i become grumpy and upset. for instance, if i make plans (in my mind) and don't tell anyone about them, when someone else makes different plans (without knowledge of the plans i have made), i find myself becoming upset. then they ask what's the problem, and i say, "oh nothing, i had different plans," which complicates things more. i need to learn to either share my plans earlier, or change them and not share that there were plans to begin with.
that is what happens in my mind all to often.
