if you don't want to fall off the tightrope, just keep moving forward.

it's weird. weird how people come and go. they occupy a part of your life for a certain time, then before you realise it, they are not there as much anymore. off to occupy a part of someone else's world.
then again, it's what we believe. we don't know they don't ever think about us, or the moments we may have shared. but that's all it is now, a memory. it's sad if you really think about it. sad when you appreciate that these people had an effect on you, helped mold you into the person you are today. made you laugh, cry and live. it's hard to let them go and can be a mistake to let them. 
but it's like miss robinson says:

"it's how life works me is afraid hun. you learn from it and move on."  

and that's really all you can do.
