Do you think people are sometimes brought into your life for a reason?

About 4 years ago I went on business to Charlotte NC and when I was checking into my hotel I was I met a person who invited me to go to the Panthers game with his friends, this was 2 years before I got my daughter but I think I was always met to meet this person. My daughter that I adopted has several genetic disorders and had seizures last year is also mentally delayed. This person works is a teacher of special needs teacher for kids like my daughter and we have always kept in touch since we met 4 years ago via email and instant messenger. I just think I was to meet him to have someone to talk to and get advice from regarding my now daughter. He tells me as it is when I feel like early intervention is afraid to say something. Do you have anyone in your life like that? That there was a reason for you meeting them, even though you didn’t know at the time.
