Haha, these are great!
Other possible "professional" career-oriented reasons to go back:
- need to get some practice on cold-calling people
- wouldn't hurt to get in some chair-stacking practice
- public speaking and hand-shaking practice
- learning (or re-learning) how to tie various ties and knots, or scarves for women
- learning how to sit attentively and even take effective notes while bored out of your mind
... It is actually really difficult to think any reason(s) to return to such an insulated, hateful, narcissisticly-controlled and subjugated environment....!!
