1) That moment while walking up from the train station to the office, make eye contact with another bowler hat wearing city gentleman, and exchange a hat tip.  This has made me oddly happy all day.
2) Talk of Halloween costumes at work that led me to dig out this page selling dust sheets.  Somewhere there is a comersal photographer who deserves a bonus for this moment of genius.
3) Meeting up with an old housemate for a drink, natter,and so I could fix the email configuration on her new phone.. Something I managed to do smoothly and efficiently.. go me.
