*If you get an email from me outside of the 9-5 it is *not* because I'm
always on or expect an immediate response from you; it is because of work
flexibility
<http://www.inc.com/john-boitnott/how-flexible-hours-can-create-a-better-work-life-balance.html>
.  Evening and weekend emails are a sign I allocated some regular working
hours for other things (such as family, gym, friends,...).  And I encourage
you to feel free to do the same.
