You are a good person. Very sweet to look after your son and his family.
I thought that as I grew older, I would become more mellow, patient, and forgiving. Nothing could be further from the truth...lol, except when it involves my 3 grandkids.
I know my interactions with my granddaughter will benefit both of us. She'll get used to my voice, and her mind will be stimulated, just hearing what I read to her. It will be therapeutic for me, knowing my problems pale in comparison to what she's going through.
Being known as "Opa" to my grandkids is a reward unto itself. The other two love coming to my house: "what happens at Opa's House, stays at Opa's House."
