Mooches ? ? ?

Ok its been a few days, but with no viewers its tough to get motivated to write for the masses (or lake there of in this case). But I figure Ill just use this as a public journal of sorts.
For today's rant I'm going to speak about mooches. We all know them, some are friends, some are family, you may even be one yourself. One of the things that crawls my skin is someone who interjects them self into situations knowing they have no means of funding the said activity. How many of you out there know someone that when events are being planned whether it be a trip or gathering of some sort, one person that is gung ho and them when time comes to pay for it all they have nothing, or to take it a step further, they may even be the one planning things and inviting you! now understand i dont mean just a simple broke friend because thats is not really a problem if you mention you cant afford it or whatever it may be and you are invited anyway and are taken care of but the ones that show up and don't say a word till its time for the bill "hey i don't have any money you got me right ".......i mean wtf is that ? ? ? If you don't have it stay your ass home , and if you even mention it before hand 9 out of 10 times your friends may have your back, but waiting till your already in it, you know damn well what your trying to do. Now people is this just me being selfish or greedy or whatever ? what are your thoughts ? ? ?
