Silence matters. Our silence matters. There are absolutely times for us to be silent - and for us to listen. Especially when our grandchildren (and grown children) have something they want to tell us. Now, yes, when they are young, the things our grandchildren may want to tell us about may not be "life-shattering", but we need to listen. If something matters to them and they want to tell us, we need to listen. When we listen to them while they are young, when they are older and have something important to talk about, they are much more likely to tell us if they have experienced how we listen to them. So be silent. Listen. This is something which matters.
With this in mind, know also, words matter. Our words matter as they have the ability to impact in positive or negative ways the ones who hear (or read) them. This is so very true when it comes to our children and grandchildren; we must be wise and choose our words carefully, so they are able to encourage, give wisdom, and always communicate our love.
Sometimes as grandmas (and grandpas/parents, too) we need to be silent. Sometimes we need to listen, and sometimes we need to speak carefully and use wise words. It all comes with the "job description".
