/ \ There a A LOT of people out their who either get comfort from, or enjoy, dumping their garbage on you. They either want to go on and on about all their problems or want to shoot down all your dreams by telling you how you can't do this or that, or shouldn't be doing this or that.
In the end, it is all the same - they have drained your positive energy and walked through your mind with their "dirty feet," more commonly known as negative energy.
Most of us allow this to happen under the assumption that we are just being nice, but we shouldn't do this. We have to look after our own welfare first.
