REMIND ME HOW TO USE AN UMBRELLA

It's raining in Bangkok this morning for what seems like the first time in ages. I guess it's around two months since we had anything substantial in terms of rain, so it does make a pleasant change.
The taxi ride into work reminded me of a wet Monday morning in Wokingham - except for the fact it's so humid here. The BBC weather website says it's 29 degrees C and misty with 85 per cent humidity. It also forecasts a high today of 34 degrees C.
It's the first time this year that I have felt the need to bring an umbrella to work.
