What’s in my rucksack?

I’m eschewing the Friday Five in favour of a meme that the FF for this week seems to have revived.

From left to right, top to bottom, here are the items in the photo.

1. Rucksack. The brand is Herschel. It has a lot of internal pockets and carries a crazy amount of stuff, while also being pretty slim profile.
   
2. Noise-cancelling over-ear headphones. I cannot live without these and have no idea how I survived many years of long commutes on public transport before I bought them.
   
3. Coffee cup. Collapsible! Purchased from my favourite barista, a one-woman outfit operating out of my local train station.
   
4. Toiletries bag. I didn’t empty this out. It contains lip gloss, medicine, hand sanitiser and hand lotion.
   
5. Red pen. For correcting mistakes, many of which are my own.
   
6. Tipex. See previous item.
   
7. Laser pointer. An essential component of my job is lecturing and giving talks. There is never any guarantee that a laser pointer will be available alongside AV equipment, so I carry my own.
   
8. Pen. A freebie from a workshop or a conference, usually.
   
9. Multi-tool. This was a freebie from the Maui conference. It has lots of little swappable magnetic bits inside. I have only used the screwdriver bits so far.
   
10. Paper clip. You never know.
    
11. Notebook and pen. I go through notebooks (again, most of them are freebies) every couple of months. This is the latest in the series.
    
12. HDMI-to-USB-C cable. There’s no HDMI port on my laptop.
    
13. Two memory sticks. I borrowed the blue one from a colleague about two years ago and am now too embarrassed to return it. The minion is mine. He used to have trousers, but they fell down a stairwell and were lost in a basement.
    
14. Lucky pinecone. Keiki gave me this when we were in California. I carry it in one of the outer side pockets.
    
15. Packet of biscuits and a mango lollipop. Emergency food, which will probably be eaten by one of the children.
    
16. Macbook Air. Laptop from Institution A, my primary employer. I also have an HP Windows laptop from Institution B, my other employer. I am mostly indifferent to the Mac / Windows debate, although I will say that the Macbook laptop’s trackpad is far better.
    
17. Railcard. The train apps for railcards and tickets are notoriously unreliable, especially when you don’t have a good internet connection, so I still carry paper copies.
    
18. Glasses case. At the moment these contain my sunglasses, which are prescription and which I sometimes wear in winter to cut the glare from headlights when I’m driving. My untinted varifocals are usually on my face.
    
19. Universal adapter, USB cables, and a handful of coins. I prefer to be equipped to take advantage of charging points whenever I can, especially since I travel so much.
    
20. Fan. From the Louvre, featuring the Mona Lisa. Very good for public transport.
