My cousin wanted to buy toys for her son, because I took her to the toy store that I was a regular customer. As we were walking around, I saw presents storing in a large glass box, so I asked about it. The salesperson tells me that these were gifts people bought for sick kids at the Cancer Center. Whenever the box was fully, they’d send the gifts to the center. I loved the idea so many that I decided to buy one of the gift. I found a nice one which was a bit of expensive, but I believed any kids would happy to have it.
