Ask a colleague about their vacations, and they will probably greet you with an empathic: “Short!" Time flies when you're having fun.
That's a typical conversation between colleagues after returning from vacation. You're living on a permanent Sunday, and suddenly, Monday slaps you in the face. You need to switch from waking up to sunlight on your face to the sound of an alarm clock (the worst sound ever, in my opinion).
You must trade cocktails and ice creams for coffee on the office balcony and your flip-flops and jams for traffic jams. It’s a lot to handle, and these feelings are more common than you think.
