What is this song about? I can't find an answer anywhere aside from possibly about suicide.

I work with different colored stocks, such as red, green, blue. I was wondering if it is worth it to make a profile for each color or just working off of a white profile would be best. I have about 30 different colors that I work with so I am not sure if doing a profile for each would work or be worth it?

I want to replace all of the locks for my multiunit. It would be best if I could find some locks that have different keys per unit but I would like to have a master key so that I can access all of the units with 1 key. Is this a thing? If so, where can I purchase these sets?
