So many friends so little time

Why is it,  that it is so hard to make time for dinner with friends?  I have some wonderful friends that I want to spend time with, yet I don't seem to ever get to spend the time I want with them.  Days, weeks, months and even years go by without that talked about dinner.  There are emails and a few phone calls, but with friends like I have I want more.  There are a few friends that live close by and our schedules work well together so I get to spend time with them.  I am so thankful for that time, but what about all the other treasured friends?  When will I get to spend time with you?  Let's get a date on the calendar...e-mail me with what dates work for you and lets get something on the calendar.
