The weather was very strange and beautiful--just at freezing, and foggy, which produced ice crystal formations over all the trees (see below).
Of course I always have peanuts in my purse, so I dragged him over to the quad where he discovered the joy of hand-feeding squirrels.
First tentative squirrel approach:
I somehow "forgot" to mention to him that rather than holding peanuts out on the palm of one's hand, as for a horse, one must stick the peanut out between finger and thumb. Squirrels have terrible vision, and if your fingers smell like peanuts, they will think the first thing they encounter sticking out is the peanut. This led to a minor nibble. However, TheLimey was very brave and persevered in the feeding attempts.
He may have been paying the squirrels back for the nibble with this bit of squirrel teasing.
(Whereas I will actively go out of my way in order to get the peanuts to the squirrels:)
A serious and scientific examination of the curious crystals:
