If you see someone on their own, just say hullo.
The commercialisation of Christmas might be good for business but is terrible for those who are alone. Every ad showing perfect families and friends must be a little like a dagger for those not lucky enough to have family and friends around.
The number of solitary people who end their lives at this time of year, especially in winter, is terrible.
To all those yet to have their Christmas Day and the rest of us heading for the New Year, seasons greetings to you and a Happy New Year.
