I've been working from home exclusively for the last year - I thought it was such a perk when I got the job offer, but I really miss the energy of an office. My best friend is someone I met at work! I miss grabbing a drink after work, passing people in the hallway, running to Starbucks with my coworkers to gossip about people in the office, the physical presence of team. It's really tough to establish new relationships with coworkers when you have to do so virtually.
