Pets can tell when you're stressed, upset or nervous. They will always try to comfort you, by trying to rub against you, crawl up on your lap, give you a kiss or just do something silly that makes you smile.
Actually it's what changed my life - I changed everything around me and work at home now because the loves of my life are here and the only 'people' I want to be around 24/7. This is work/life balance for me and I only wish I had done it sooner. Re-jig/renegotiate job roles so that it allows you to work from home instead of having to go into work elsewhere. There ARE ways around things, you just need to find them :)
