When you are attached to physical goods and various bullshit, it's hard to leave everything behind. You can always make a plan for a limited time ad come back... nothing is forever, right? People around you will be there anytime you need, if they are really honest and transparent with you. Otherwise, you'll automagically lose them on the way to nowhere. A phone call or sms it's always at a fingertip away for both parties. There are no excuses for not contacting your loved ones and saying hello.
