If it's there and you can see it - it's real. If it's not there and you can see it - it's virtual. If it's there and you can't see it - it's transparent. If it's not there and you can't see it - you erased it!
A man left work one Friday afternoon. Being payday, instead of going home, he stayed out the entire weekend hunting with the boys and spent his entire paycheck. When he finally appeared at home, Sunday night, he was confronted by a very angry wife and was barraged for nearly two hours with a tirade befitting his actions.
Finally, his wife stopped the nagging and simply said to him, "How would you like it if you didn't see me for two or three days?"
To which he replied, "That would be fine with me."
Monday went by and he didn't see his wife. Tuesday and Wednesday came and went with the same results.
Thursday, the swelling went down just enough where he could see her a little out of the corner of his left eye.
