    I had always heard that North Americans value independence, and that Europeans value, togetherness. But I never fully understood it until 2 months ago, when I left my Ph.D. lab in Canada for a 4-month research in a lab in France. On my first day, Pierre — a Ph.D. student whose desk is across from mine — tapped me on the shoulder and asked: "Coffee?" I nodded and followed him down the hallway to the common room, where other grad students were filing in. I sat there, cautiously sipping the bitter liquid five times stronger than my normal Americano and trying hard not to reveal my uncultured tastes, while lab chatter（闲聊）filled the air.

Coffee breaks are a routine part of work life here. The chatter sometimes turns to serious scientific topics. But mostly, the meetups offer a chance to unwind — to share stories about life inside and outside the lab and to connect with people who understand what you're going through.

The lighthearted atmosphere and sense of community is a welcome contrast to my life in Canada, where I spent most of my workdays all alone. I went into the lab each morning with set goals for my day. At lunch, I'd keep my eyes glued to my computer while I shoveled（大量送入）forkfuls of salad into my mouth, trying to power through my to-do list.

Our lab held weekly meetings where we'd take turns presenting our latest, work and getting feedback from colleagues. But we didn't take daily coffee breaks. My labmates and I were too busy collecting data and publishing papers.

Looking back now, I realize how much we were missing. Researchers need community because good ideas don't just come from reading literature and thinking deep thoughts; it's helpful to bounce ideas off others, particularly in a nonthreatening environment. It's also helpful to have a spot to share the day-to-day ups and downs of life as a grad student. How else are you supposed to know that you're not the only one suffering from challenges like anxiety?
