Honesty is the best policy.
People c'mon now, if you don't want to do something or something is bothering you open up your gianormous mouth, you sure know how to use it when your insulting someone or picking a fight, why not just say, No Rosita I don't wanna go to your house to day, I don't feel like it don't have me making my plans involve you & have me thinking for a whole week its going to happen and in the end you flake. I could have bety my life it was going to happen and it did, and you made it seem like me , but guess what I'm done bending over backwards and making the extra effort when you don't even give a rats behind. Thanks a ton.
Can let these people mess up your day, you have to just brush them off..
