I don't like

The Insert key.

Let's be serious, no one knows for sure what it's real purpose is. The only thing we can be certain about when it comes to the insert key is that it is equivalent to a hungry alligator and the devil. Nothing is more frustrating than realizing that you just typed over a fully completed sentence because you accidentally clicked the insert key.

For those of you who might not have spent much time on the computer typing let me help you understand the insert key. It sits amongst six other keys. I like to think of them as brothers with the insert key as the deceitful, evil brother. Now the sole purpose of the insert key is destruction so once it has been activated it will destroy anything in it's path. Let's pretend that I just typed the sentence "Grandpa ate fourteen pats of butter" and that I wanted to add to the sentence. I would drag my mouse and click where I'd like to add a few words. The second I start to type the insert key would start it's mischief.

"Grandpa ate fourteenhundrend butter"

That makes no sense, what happened to the 'pats of'? Oh I see, the greedy insert key ate them!

and that's why I hate you insert key.
