Dangling participles.

me/my I have heard both. The me construction may be a readaption of you don't want me to tell your age. I guess I was taught that the my version was correct, too, but it doesn't seem to bother me all that much. It's like different than vs. different from or even different to. If rbarr (http://wordsmith.org/board/showthreaded.pl?Cat=&Board=words&Number=19694) were here she'd explain it all as dialect differences and choosing different models for a new construction, but she's not so we'll just have to fumble through for ourselves.
