....you try to unlock your front door by waving your key card at it and wonder why you don't hear that familiar beep.

pmsl ........ laughed out loud at that one done it loads of times .......

You know you spend all your life at work when........

......when you answer your home phone with the usual answer that you use at work....

....When you...set your alarm for 6am on your day off.

when you dream of clients and think hey! I don't get paid for nightwork

.... you don't seem to have any time to socialize and have to rely on the internet for a sane/insane conversation

You attempt to give your children a detention!

.....you press 9 to get an outside line on your home phone.

When my son walked into the lounge and I said to him "Yes? How can I help?" (while backing him out the door, clients were not allowed in the office at work).
(that was the day I fell asleep on the toilet seat and broke a rib, and handed in my notice the following day).

I'm cringing now, because in the past I too have been guilty of pressing 9 on my home phone, tried to open my front door - in fact once my fridge even - with the key card, set my alarm early for my day off and even flipping dreamt of clients.
And once, at the bank I had to fill out some forms and I knew my work address right down to the post code but I couldnt remember my house number or the post code where I lived.

Your spending too much time at work when you serve dinner in a lunchbox.

...when you're still at FB

I've done most these, especially answer the phone and say the company name

Also drive somewhere on your day off, and you automatically start taking the route to work

When you answer the phone at your new work place with

"Hello, *name of the company that you used to work at..*, Laura speaking"......
