I must admit to being someone who sometimes cancels at the last minute, sometimes im tired, sometimes ive over stretched myself and sometimes ive not said no when I didn't want to go and then back out later..................... and I agree because I do it, I don't mind when my friends do the same for their own reasons, I just do something else.
And I also know my friends and I would be there if needed no matter what............so I suppose im saying if you are a good enough friend let it go or perhaps mention that when you book something with me, please feel free to say no if you don't want to come really!!!
