I have a question regarding the future perfect tense and which prepositions go with it. Understandably, by, for, and in work very well with the future perfect.
By friday, I will have been working here for one year.
In two years, I will have worked here for two years.
However, my question is whether or not since is usable with the future perfect.
"Do you want to go out tonight?"
"Nah, I'll have been working since 9 AM. I'm going to be dead tired."
My guess is that this is usable as an approximation. I'll have been working here since May for example. Swan and Cambridge offer no solution for this. My question is: is this possible?
