We all carry opinions and ahum (me too), we sometimes overdo it. Sharing an opinion on something can easily be seen as a big mouth saying bla bla bla.
When I think about it a little longer I reconsider the stating of an opinion. The person who hears what we say interprets the message and can make it into bla bla or as something lovely. Or something horrid, something regular, something abnormal whatever.
I would love it if I can listen to others and hear what they say as a contribution. However hard that might be for me. If people state an opinion could it be that they are concerned or passionate about something? That they are touched by it and want to say something about it? Even so called negative opinions can they come from the heart? It all depends how we interpret an opinion. What do you think?
