How do you know when its time?

I have a question for all of you readers out there....how do you know when its time to cut ties with people in your life you bring in more drama and negativity than they bring in good?

Now don't worry those of you who I consider my friends reading this I am speaking in hypotheticals here nothing drastic like I am looking to cut you out of my life.  But honestly when is it the right time to just let those people go, especially if you have known them for awhile?  Do you just slowly phase them out, make plans without them and hope that they catch the hint?  Do you just come right out and say I don't need your drama and your negativity anymore and walk away with a clean break?  Its a hard choice to make and I was curious to know what the mass populace of my faithful following think...

I know that at sometime or another many of you have wanted to cut that person (or people) out of your life for a long time, or even for good.  How do you do it? I know the way I would want to do it but I am running out of room to hide the evidence....j/k! 

Until next time my friends take care!
