pine in red vase

Someone gave me a box of vases yesterday and most of them were things I would discard myself (bud vases from the florist, etc.), but one was this great red vase. Used it on the windowsill this afternoon with only pine (pine I picked up on my walk) in it. I'm now sure squirrels gnaw the stems of bundles of pine needles like this, because you can see where they've gnawed and there are bundles like this all over the ground. This is actually half a dozen bundles.
