My favorite verb tense is the future perfect because it is the closest anyone gets to real time travel. When used, the speaker of the statement exists simultaneously in two times: the future and the past.
"By this time tomorrow, I will have left town."
The action is past but the time of its occurrence is in the future, and the action itself is a phantom of what occurred. The speaker is not in town, but the lack of him continues to be in the town, which makes him a ghost.
I am interested in ghosts, time travel, and leaving town right now.
