Then have those hurt feelings fester into a monster that erupts months of years down the road, only to unintentionally hurt someone you love the most.
What about having a strong opinion about something and afraid to say anything for fear of what others will think of you?
Then later wish you would have opened your mouth and kept someone from making a big mistake because they thought you were okay with it.
It has been my experience that it is best to communicate our feelings and opinions early on, nip it in the bud as they say, while it is still raw and fresh. But with tenderness and much love. Especially with those we love and care for, they deserve it, they earned it, it is a healthy practice for all parties involved.
Communicate, communicate, communicate.
