u know u r a geek when :
1.you are reading a book and look for the scroll bar to get to the next page.
2.you look for a icon to double-click to open your bedroom window.
3.when asked about a bus schedule, you wonder if it is 16 or 32 bits.
1- I use the term "geek" instead of "nerd"
2- When i'm at the super market i want to use CTRL+F to find something, but i cant.
3- I solve my computer/programing problems when i'm in the shower, always worked for me.
