In this day and age I consider knowing one another's names, what the other looks like, and having held a conversation to be meeting someone.
And you're serious? Time off is good for people, it is good for your mental health (especially if you have a stressful job) and gives people something to look forward to. Not everyone gets those 20 coveted days off, temps get fuck all, and more and more lower-level jobs are only temps and not full-time. Yes, the reasons might be outdated, but people need a break.
