If for any reason you are in London and are struggling with the virus, please be aware that buses may not be entered at the front (to protect the driver).
Use the middle door, let other passengers off first (at a sensible distance), there’s no need to swipe in and take your time as there’s no hurry.
Bus doors have big stickers on telling you what do to. And do spread out inside the bus.
Even better, stay home.
Ages ago I wrote a blog about how to get onto a London bus: http://www.pwsanders.co.uk/2018/08/12/the-big-red-one/
The Boris bus has changed, due to passengers cheating the system and not paying for rides.
So now, instead of getting on using any door you may only use the front door.
One of the great things about being in a big city is the choice of museums and galleries available. Actually, I know people who would refuse to go in any gallery regardless of what it is about, but I am sure they are in a minority.
Here in London we have some great places to visit. Some are free. The National Gallery, the British Museum, the Science Museum and the V&A are. If there is a special exhibition on you will probably need to pay and I suggest booking in advance (on line) to avoid disappointment.
For most places there will be security checks and limits on bags that can be carried around.
