Why do people steal

Veronica • George Alek Jr 4/08/17💙 Layla Jae 8/16/2018💜 Currently pregnant due in November

So my brother's babygirl was born a week after mine was born. She was born with down syndrome though and was also their rainbow baby. I ordered her two bows recently. One rainbow one and one down syndrome awareness from an etsy shop. They were delivered in their mailbox yesterday but they live in a sketchy area..and my sister in law call the post office too..the bows are no where to be found. I cant believe people have the audacity to steal and then they have no idea what the bows were suppose to mean to my brother's family. Ughh I'm so upset😞
