No two people are alike

 We may be similar but no two people are exactly alike. Not even identical twins. We each are unique. We may agree on some things but we don't agree on everything. Our differences are what makes us unique individuals. If we were all the same there wouldn't be any new inventions. It also would make things boring when you don't have anything new to talk about. We all have things that we are good at as well as things we are not good at. Luckily you don't have to know everything because you can always find someone who does know that you can ask. We can all look at the same thing but see something different. We can all hear the same thing yet interpret it differently. It doesn't mean that someone is right and someone has to be wrong. It just means that right or wrong we see what we see and hear what we hear. Don't let a simple difference in opinion over something that isn't important, destroy a relationship that in your opinion is important. Just because one person is a vegan and the other person isn't doesn't mean they can't go out for dinner together and have a good time.
