Alan: Can you send me the file with budget estimation
Allison: Done
Alan: Sorry, not this one, estimation for current year, not for next year
Allison: Sorry for the mistake, sent it to you
Alan: Thanks. Tell me, do you know, why we doubled the costs in the line "other expenses" compared to last year
Allison: It was when our boss had to come back from Japan for the convention
Alan: I see, I see...
Allison send Alan budget estimation for this year. Extra other expenses are boss's trip to Japan, for a convention.
