That second text-- "Have u Walked buddy"-- is enormously clarifying. I understand now that when she said "Walk buddy", 404 didn't mean that she wanted Leila to accompany her on a walk-- she meant that she wanted Leila to walk a dog named Buddy. I feel much better having puzzled this out.

Unfortunately, we now have a new quandary; namely, what are these W's with question marks after them? I know sometimes people will text "Leila W." and then "W" will end up in the text body (instead of in the "address to" line)-- but "Leila W?" That is not an initial.
