Here in Norfolk there are numerous oak trees. Now they're producing acorns, and as my husband drives me about in his nice car, acorns drop onto it, risking damaging the windscreen and the paintwork. Also, sweet little grey squirrels are scurrying about collecting them up for their hibernation snacks later in the year.
Actually, I love oak trees. They were planted a few hundred years ago all around the farmers' fields to mark the boundaries. But in Taverham (village near ours) they built a huge new supermarket (Aldi) and felled about ten gorgeous old oak trees. I actually shed a tear when I saw the stumps.
