Percy Shelley’s earliest known letter, written shortly before turning 11-years-old, was an invitation to his cousin’s aunt to accompany them on a family picnic. He signs the letter with “Now I end. I am not Your obedient servant, P. B. SHELLEY.”
We have proposed a day at the pond next Wednesday and, if you will come tomorrow morning, I would be much obliged to you; and, if you could any how bring Tom over to stay all the night, I would thank you. We are to have a cold dinner over at the pond, and come home to eat a bit of roast chicken and peas at about nine o'clock. Mama depends upon your bringing Tom over to-morrow, and, if you don't, we shall be very much disappointed. Tell the bearer not to forget to bring me a fairing, — which is some ginger-bread, sweetmeat, hunting-nuts, and a pocket-book. Now I end.
It’s interesting to note how this short and simple letter manages to showcase several of the most important elements of Percy’s character having been cemented at such a young age — his rebelliousness, his humour, his love for people and community, his descriptiveness, his directness, his eccentricity, and his propensity for female company.
