I hate this. Honestly. Indecision is really not becoming to you. Make plans, and stick to them.
You've put me through it, almost 1/2 the times we make plans, you cancel, or are late, or whatever. And you know what, you are one of my best friends. But this is total bullshavicks... I'm so effing sick of you blowing me off. I'm sick of calling, and your phone is off. I'm sick of you making plans, and then "Oops, I totally forgot" Or "Sorry, I'm sick" or "cleaning" or some other lame excuse.
Most likely, you didn't double check with your mom about something, and then she gets pissed because you are using her house without asking, like usual, and then you have to fudge up every one else who had plans. Why can't you just say, "Hey mom, I want to have a party Wednesday afternoon, is that OK?" And if not, find a better time, and then STICK TO IT.
None of this bullshite oh, it's at 1 pm on Wednesday!
and then two days before: 3:30 on Wednesday!
and then one day before: Next tuesday at 1!
and then again, just kidding!: Wednesday at 1~!
and once more: Wednesday at 2!
and one more time for good measure, the day of: Wednesday at 3:30!
and I bet someone reading this will think I'm taking this out of context and stretching it... IF ONLY. This is the shite she pulls (excuse my language I am just incredibly sick of this). And it's every time she makes plans. Everyone has to be happy, which isn't possible. She better learn this before going off into the real world.
Make a stand for what you know, stand your ground, don't get pushed over by the lightest breeze or you will never become full grown.
