Honestly, I don’t think you can play too much HL.
When you look down at the ground and are surprised you’re actually able to see your own feet.
When you hear the same type of alarms as black mesa and you go to get your crowbar.
But seriously i fucking love it when i hear those alarms, makes me smile, for all the wrong reasons.
When you take objects in your hand and try to look straight ahead and hit stuff. C’mon, ya know ya do it. 
I tried it :3
When you attempt headcrab zombie poses/walks in front of mirrors.
when you think having a PhD in theoretical physics entitles you to a shotgun.
When you carry objects in front of you, arms outstretched, and bob them around as you move.
When you actually fucking minor in physics, solely because you think someday that knowledge will make you a geek turned hero and savior of man…
When you shop for awesome retro glasses at the optics center.
When you get a lambda tattooed on your wrist… :I
I really want a blackmesa hoodie. With Lambda logo on the back or something with the words Science Team underneath
A while back at work, (i worked in retail) i was filling a shopping cart with misplaced merchandise. At some point i’d tossed a vibrating cat toy into the cart and accidentally set it off. A few minutes later, random items in the cart were moving all over the place, the toy was bopping around the cart and making a terrible racket. A customer stopped and asked what was making all the noise. My answer?
“Physics glitch.”

To quote from one of my posts in another forum about the same topic…
“When you live up to your family name and face full-life consequences.”
It doesn’t? :o
I can see myself doing that. I can.
…When you take all the flashlights in your house down to the basement at night to see which one is closest the the HEV suit’s flashlight. (turns out its one of the bigger ones)
actually 4 halloween i carved a lambda into a pumpkin along with a fail “ima firin mah lazor”
without Half-Life I would be dead
when co-workers start looking like Alyx Vance.
When watermelons are fed to pet hermit crabs.
when questioning irritating bits of work clothes seems entertaining.
when guards look like veritable target dummies.
when crowbars are kept for safe keeping in an extinguisher cache.
Win.
Sig’d for pure awesomenesss
Edit: It’s too awesome for me to sig =[
Sig that.

When you recite the formula for Newtonian gravitational force every morning during doctoral research on entanglement and quantum chaos (LOL Freeman’s mind)
or when your coworkers are all dead.
