How many Goodgym r unners does it take to change a light bulb

One runner ran to MrsV to change a light bulb .On arrival Mrs V showed me the bathroom light that had gone as she had some steps I soon had the cover off and the bulb out and on my way to get a replacement. I soon was back and had the replacement fitted and cover back on I showed them that it was working and had a chat we said our goodbyes and I was on my way knowing that she was ok .
