Our initial plans for today (and we had a few) did not shake out at all. When we left the house bright and early around 1pm
— our internal clocks are still heavily delayed by the pesky jet-lag, I noticed a group of men outside our building, beers in hand. My immediate thought was “Oh, no! It’s Ascension Day” — which happens to also be Fathers’ Day here, and German fathers generally celebrate by lounging about all day with beers in hand, presumably to rest from the strenuous parenting they put in every day 
This also meant that every store is closed, as well the weekly markets — one of which we wanted to visit to get our sourdough fix & maybe pick up MOAR cheese and other sundry items. Nope.
We scooted northeast anyway, just in case, but the light traffic and dark storefronts we passed en route increasingly dampened our hopes to accomplish anything on our agenda 
We finally turned around and headed back to our hood, where a Späti (a small shop with essentials like booze, cigarettes, other beverages and the odd household staple, which has a special license in Berlin to be open at hours other stores are not) provided more water, beer, and a Very Important pistachio bar 
The ower informed us that today was neither Ascension nor Fathers Day (that would be May 29th), but the 80th Anniversary of the Liberation from National Socialism, which was scheduled to be a one-off, Berlin-only day of remembrance by the German parliament in 2023. A worthy day to remember if we are ever to learn from the past. Not holding my breath, personally.
We had our breakfast at home, then, after our 1-hour chilly scoot through town, where we also discovered this, oh my! 

No plans to visit, in case you were wondering.
Freezer spelt rolls with an abundance of seeds baked to crispy perfection in our oven, liverwurst, German bologna, smoked ham all from certified humane producers — a thing I very much appreciate about German supermarkets, some of the leftover cheese nubs, SBEs & delicious cold milk.
