Nightly visitor

What was the closest you’ve been to a wild bat? For me it was about a metre. Last night, one somehow found it’s way into my bedroom through the open window and the gap below the blinds and then was frantically circling around the room, unable to find its way out again. It was so cute! Roughly the size of my hand with its wings fully open. It was bloody fast. It took me a while to see that it wasn’t some huge insect from hell about to eat me, but instead a cute little furry bat. And it was completely silent. So amazing. But, I don’t want to know what would have happened if I had been asleep already. The poor fella likely would have completely freaked out. Luckily, I wasn’t and everything went well. I got up, opened the blinds and in the blink of an eye, it was out again. Literally. I didn’t actually see it leave and was worried for a bit that it might have landed somewhere to hide.


What I like about cycling

  • It’s faster than walking.

What I don’t like about cycling

  • Umbrella incompatibility when it’s raining.
  • Sweating when trying to get somewhere fast.
  • Certain car/bus/truck drivers.
  • Potholes.
  • My bike chain coming off every few days.
  • My extremely squeaky breaks.
  • My bike getting stolen. 🙁

“Old women’s summer”

 Altweibersommer, aufgenommen in Niedersachsen im September 2006, trees and gras with cobwebs

Altweibersommer (Wikipedia)

It’s warm! We’re in the middle of “Altweibersommer” (German: old women’s summer). The phrase probably comes from the word “Weiben” for weaving or cobwebs, and not “Weib”, that is wife or woman. In either case, it’s related to the silks, which some spiders use to fly to a new place, particularly this time of the year. They do look a bit like the hairs of old women, don’t you agree?

If you want to know more about Altweibersommer, you can check out the German Wikipedia, or look for the equivalent phenomenon called “Indian Summer” in English.

And don’t forget to enjoy the sunshine!
