Stupid Stupidheads

So, apparently just going to lunch without letting me know at all isn't enough any more. Now, I can be sitting 10 feet away, and if I get a phone call, nobody bothers to see if I'm in the lab, they just assume I'm not. Um, what? This has happened at least 3 or 4 times now, and I am only willing to believe that one of them was an accident. Am I really the only person who actually LOOKS for the one getting a phone call?
