We love spending time together but maintain our friendship and family ties because these other ties make us balanced and well rounded.
The older we get, the less time I expect to spend with my friends. We hang out when we hang out.
Careers, significant others, husbands, children, wanting to twiddle our thumbs up our own asses instead of hang out...whatever's whatever.
We will talk to each other regularly and try to hang out once a month or less, depending on our fun schedules.
