Inventing time machines must be the best job ever, because once you built one you can just travel back in time to before you did all the work and already be done. I assume the only reason people are not going to have been doing that is because time travel really messes up all grammar.
When I build a time machine, I’m not going to tell anyone about it at all, and apparently I already haven’t.
Also, I just started reading recently, I love this strip, and I’m very upset with future me for not having told me about it sooner!
Well I hope your future self is going to have been enjoying this for a long time. 😀 Welcome.
