You don't get out of your tomb much.
We're not saying you're a grave robber, but if you are: seriously, stop doing that! So before you start robbing graves, consider who you're affecting with your actions. Take advantage! You're hanging out, just chilling, neatly swirled in your mummy wrappings, and suddenly some guy starts creeping in your tomb, looking at your golden urns or your Xbox or whatever else a mummy keeps in his tomb. Or burial tombs, or sarcophaguses (hmm, or is it sarcophagi? Because, aside from the fact that it's incredibly rude, you also have to worry about mummies. And maybe the guy doesn't take anything, but more importantly how did he even get in your tomb?.
