True of all parenting, sometimes it's easy to forget. I'm not a grandparent yet but I'm sure there will be moments just like I sometimes thought in wonder goodness I sound just like my mother there will be moments I see my daughter as a Mum & think goodness she sounds just like me. So yes lets set a good example.
If you have good thoughts they will shine out of your face like sunbeams and you will always look lovely - Roald Dahl
They say that ...when you find yourself, try to become a better person all your shitty friend ...well, they will be gone. God will not allow you to work on you, let you get better and heal and keep bad friends that influence you the wrong way. that is not going to happen.
