I typically post these on the travel blog - I haven’t updated it in a while and well…

London

• London Walks are good. Specifically if you talk to people along the way amidst the guide’s loud voice. I don’t know how other people managed.
• Walking near Thames at night without a jacket / extra over shirt is a good experiment - not to be tried again.
• Spending more time in Galleries and Museums than you originally planned is good. At least you take away to your satisfaction than running around and visiting 100 places in a city in a jiffy.
• You meet lots of interesting people in Art Galleries. This is true for all walks of life, but Art Galleries rank higher in probability.
• No luggage trolleys at Heathrow Express station can be an interesting situation, specifically when you have 3 bags to take care of. Always helps to ask people, even the Express staff. Didn’t have enough time to talk to the person who helped.
• If you get a strange kind of (unidentified) feeling, calling up friends to say ‘Thanks’ is a good thing to do.
• Getting an autograph from the recommender of a book you bought brings nice pleasant surprises in Art Gallery shopping areas.

This is just the beginning.
