There are several days where I had been extremely happy but one particular day that stands out is the day my parents got a puppy for me as a birthday gift.
At that time, I was 8 years old and was extremely scared of dogs and would take to my heels whenever I was within a mile radius of a dog!
Naturally, I was upset and cross with my parents that day. However, when they set the pup down, one look at its eyes and all my fears melted. I tentatively took her in my arms and cradled her as she… snuggled in my arms! To this day, that remains the happiest moment in my life.
