When you are in America, it is often complicated to keep in touch with your beloved ones in Europe due to the different time zones. Try calling them in the morning — no one’s at home (they are still at work). Try calling them around noon, they might already have gone to bed. Don’t even think about calling someone in the afternoon — they will be very grumpy if you woke them up.
But one day you will be very lucky: your birthday lasts 33 hours. It starts at 12am CEST (3pm PDT) on the previous day and lasts (of course) until 12am… So you can actually make the most out of it. Next year I’ll be in Hawaii — 12 hours time difference to Europe 😉
