I meddle. It's a bad habit, like biting your fingernails or chewing your beard, and I do both of those, too.
Oh, I'm not worried about temporal paradox or ending the universe or some such. Time is pretty robust, and it's hard to shift much of anything. What I can do is make splinters, send past versions of myself off into different trails of possibility.
Mostly I tell them, "For God's sake, call her back." Sometimes I add, "You idiot."
The more I tinker with these things, though, the more I wonder when one day I'm going to look up and see myself, older, more battered, climbing through a portal and glaring down at me, sadly shaking my head.
