"I am not leaving the house without my... typewriter!"

[Jonbo298]

Keys, wallet, a pen or 2, cell phone, gba depending on where I'm going

[DimHalo]

yeah, it depends on where i'm going...
wallet, cell phone, keys (sometimes checkbook)
gloves
my back pack is not going to be a pretty list so i'll leave that out

[The Germanator]

Usually just my wallet, keys, and a pen. Obviously depends where I am going, but those are the things I usually need.
