The group of my professor and another professor from a distant Asian country have signed a cooperation agreement.
As part of the cooperation, me as a rookie graduate student have to visit the other professor. Unfortunately, the proposed days of the visit interfere with a few days of a personal holiday. On some other time-frames it is either too late or the host professor has deadlines to work on.
The only time-frame which fits all is the one which infers with my plans.
Both the host professor and my professor in their email communication asked explicitly whether the proposed date fits me. Of course it doesn't, but I don't know if I should say that or should I simply sacrifice my plans (a weekend + two bank holidays), lose a few days of personal traveling, and opt for the visit?
