' COMMENTS: If you have ever had an issue making a decision like "What Should
' I eat for dinner" or "What should I do tonight?" then IDK aka "I Don't Know"
' is the script for you. It will randomly select a decision for you from a line
' delimited text file you pass to the script. You can run the script with Wscript
' by dragging and dropping your file onto the script or with Cscript by using
' the file path as the argument passed. You can make lists for all types of
' decisions you commonly make, and a few ideas are Yes/No, Magic8Ball, Pizza Shops,
' Restaurants, Movies, etc.
' EXAMPLE: Drag-N-Drop with WScript
'          Drag and Drop a file called Pizza.txt onto IDK.vbs to select a pizza shop
' EXAMPLE: From and command prompt with Cscript
'          C:\>cscript IDK.vbs "C:\My Lists\pizza.txt"
