Beech nuts

we were sitting underneath a big beech tree for shade and heard the beech nuts dropping faster and faster and first thought the heat but the beech nuts came showering down faster and faster, pinging on the roof almost as if someone was aiming them and reallised when looked at the nuts on the ground it was only the shells and from the mutley laugh coming from the tree that we were being pelted by beech nut shells by a pair of naughty squirrels.
