On Sundays,there are more people around the bay.I love riding my bike then so that I can give as many smiles as possible.Today,on may way back home,I noticed a little girl with walking with her mom holding a box of her things.It was so beautiful so see how happy they were.I kept riding my bike and I noticed a shiny necklace on the ground.I didn't do anything at first,but then I thought maybe it belonged to the little girl.I turned around to pick up the necklace.Luckily,it was still there,but for a second I thought that maybe it did not belong to her.I decided to go and ask them before picking it up.I turned around again,and started looking for the mom and her daughter.I easily spotted them and noticed that they were looking for something missing in the box I stopped and asked,"Did she drop her necklace?" "Yes," her mom replied."I saw it.I'll go get it." I answered.I went back and retrieved the necklace.They were very happy and the mom asked her daughter to thank me.It was the cutest moment of my day.Even though the necklace was a simple chain made of plastic,the happiness on both the mom and her daughter's face was priceless.It made me feel so good,and I am so glad that I went back to ask them.Never hesitate when you know you're about to do an act of kindness.Just go for it and it'll make you feel blessed,I promise!-
