Blackberry picking and honeysuckle.
It seems that many people are unfamiliar with some of the tastes of the countryside.  Having spent much of my childhood in the country I grew up sucking the honey out of honeysuckle and eating brambles (blackberries).  Today I did both as we picked brambles to freeze for winter desserts.
It prompted me to recollect the furore when the Oxford Junior Dictionary recently removed many names of common or important British plants and animals such as bramble, dandelion, acorn and bluebell along with many words connected with farming and food.   These have been replaced with words like blog, chatroom, voice-mail, celebrity and broadband.  Even very young children are using technology so it is right that such words are introduced, but the worry is that they are becoming very unaware of the natural environment and becoming more isolated from personal contact by using technology instead.

Research evidence showing the links between natural play and wellbeing; and between disconnection from nature and social ills, is mounting.…..  A generation ago, 40% of children regularly played in natural areas, compared to 10% today, with a further 40% never playing outdoors. Obesity, anti-social behaviour, friendlessness and fear are the known consequences. 
Julie Frusher wrote: “Nature education is so important for children – and the adults they will become. It gives a sense of respect for the earth, on which we all depend, and it also improves physical and mental health.”

“Blackberry picking”  in urban slang apparently now means stealing expensive mobile phones from peoples' pockets.
