What Perna says works well, have used this many times, they humor of catching my mom as she says it. When I was younger my mom was notorious for doing this and still does it once in awhile. I had a counselor when I was in middle school tell her that "unsolicited advice is viewed as criticism," which was so true. She didn't mean it that way, not realizing but that's how these little reminders felt as if she didn't trust me to handle even simple things. She gradually stopped but still reverts once in awhile, I just have to say, "unsolicited" now and she laughs at herself, stopping again for awhile.
