Careful with what you wish for...

Much to my annoyance a few colloquial expressions seem to try to prove them selves to me over and over again.
One in particular and a prime example is: "Careful what you wish for". May not seem bad at first but it's recurring and unforgiving.
Hey,I believe it...don't worry,you needn't throw me a dud hand or a huge crapolla of a left swing to get me to believe that these well used idioms are correct.
I for one use them regularly and never ask to see a list of happy costumers or the rate of success from usage. I believe it!
My oh my fate,Karma,whatever you wish to call yourself you sure don't like me very much or if you do you are like one of these mothers that believe that the only way to bring up a successful child is to treat them mean! You're a bit like Joan Crawford in "Mommy dearest". Grrrrr...I needn't that type of emotional scarring what I do need is that for once things kind of go to plan or at least not in such a difficult and laborious head fuck of a way.
Please let me for once get something good out of it...a good outcome from something which I've worked hard for and I have worked hard,damned bloody hard at! So that I am exhausted. If only to be realized and finished without a hitch. That's all mother universe. That's my wish. Hope your day's going well...Did I say that I loved you?
