The Queen has many well wishers as she remains in lockdown at Windsor Castle.

Among them is 7-year-old Timothy Madders, who mailed Her Majesty a letter along with what he described as a "happiness word search." In the puzzle, words that the Queen could find included "smile," "jolly," and "sunshine," to name just a few.

Timothy also wrote a note to the Queen, explaining his concern for her: "Dear Queen Elizabeth, You might be feeling sad or lonely during lockdown, so I thought I could make a word search for you to cheer you up. Love from Timothy Madders," the note read.

Jo Madders, Timothy's mother, shared with the BBC the family's delight when an envelope from Windsor Castle arrived at the family's Billericay home. The letter was written by Philippa De Pass, one of the Queen's ladies-in-waiting. It read:

"The Queen wishes me to write and thank you for your kind letter, and for the puzzle you have created especially for Her Majesty," the letter began.

"Your thoughtfulness is greatly appreciated, and The Queen hopes that you too are keeping safe and well in the current situation. I am to thank you very much indeed for writing as you did at this time."

Mrs. Madders reported that Timothy was thrilled by the "very important" letter he received. 

"He kept saying to me not to send the original to anyone else because that was for the Queen," she recalled. And it appears as though young Timothy's hard work payed off, as his kind gesture brightened the day of the 94-year-old monarch.

Previous reports have said that the Queen does "keep busy" in lockdown at Windsor Castle, where she's been with Prince Philip since March. She's also been photographed horseback riding — an activity she partakes in on a daily basis.
