For me personally, autumn is a great time. Trees are painted in deep orange-red tones; it's not hot outside like summer. The best way to not be homesick in such weather is to take a best friend, go to a cozy coffee shop, drink coffee or tea and chat about everything in the world. Everyone has a period when sadness for no reason, and when it starts to rain, and autumn is full of them, it is very convenient. You are immersed in your inner world, you hear only raindrops that knock on the windowsill. It helps to collect thoughts.
