What does it mean to obtrude someone? (From Dickens's Great Expectations)

To obtrude is to offer or force something upon others unasked.

Looking toward the open window, I saw light wreaths from Joe's pipe floating there, and I fancied it was like a blessing from Joe — not obtruded on me or paraded before me, but pervading the air we shared together.
