Questions & Answers about ای کاش شما فردا به دفتر من تشریف میآوردید.
Why use تشریف میآوردید instead of just میآمدید for 'would come'?
تشریف آوردن is a deferential compound verb used instead of آمدن (to come) when you are addressing or referring to someone you want to show respect to. It literally means 'to bring honor' or 'to bring presence'. At this level, you will start using these special respect verbs to elevate your politeness.
Since شما is plural, are we definitely inviting a group of people to the office?
Not necessarily! In the T-V system you are currently learning, شما (and its matching plural verb ending -ید) is frequently used to address a single person formally and respectfully. The context of the conversation determines if it is one esteemed colleague or an actual group.
The sentence refers to tomorrow (فردا), so why is the verb تشریف میآوردید in the past imperfective tense?
After ای کاش (I wish / if only), using the past imperfective (the prefix می- plus the past tense form) expresses a wish about the present or future that is hypothetical or unlikely to happen. Even though it is about tomorrow, the past tense structure is required to show it is an unfulfilled wish.
Can I use تشریف آوردن to talk about myself coming to someone else's office?
No, you should never use deferential verbs for yourself. You only 'bring honor' to others! If you were the one going to their office, you would just use the standard verb آمدن (to come) or رفتن (to go), or use a special humble verb for yourself.
