unsure of my welcome here, will quietly depart should there be an objection to my presence...

Having been approached, coached and instructed by an angel, I must state I have knowledge of the existence of at least one angel. That people, other than myself, have seen the angel when iel has come to instruct me, has validated my perception. That iel can choose to be observed, or unobserved, by others is also my experience.
I can share what I have garnered from the instruction I recieved to the limits of my ability to understand what I've been shown and told.
