My dear Gideon, There is so much to say about dementia. What is the answer of the church to that? Why did it hit your friend? Too much to be written in a post. Let me tell you that what you are doing right now is true christian charity. You help your dear friend, you are with her, you give her company and safety. Thank you in the name of the lord. I will pray for your friend and also for you in the intercession in tonight's holy mass.
Lord, be with us now to strengthen us; about us, to keep us; above us, to protect us; beneath us, to uphold us; before us, to direct us; behind us, to keep us from straying; and ‘round about us, to defend us. Blessed are You, O Father, forever and ever. Amen.
