I was replying to another thread when I thought of this.
Several times in the past, I've gotten the sense from family members, friends, or coworkers that this person had decided that some aspect of me was "off" and wanted to "fix" me. The most recent example has been a couple of male coworkers, who would encourage me to try new things, be more open to experiences - not necessarily a bad thing, until I took it too far and got involved with someone (a third party coworker) I shouldn't have. These people would tell me how I needed to get out more, even if I didn't feel like it, needed to be more open to love, stuff like that. And that "third party"? He had a pretty strong White Knight complex.
The most potent example is a cousin who lived with my family (basically was our nanny) for several years. She had/has issues with my mother, and wanted to try and broaden my horizons, ideally in ways that would anger and upset my mom. Since she didn't see me pushing boundaries on my own, she took it upon herself to push for me - sometimes with disastrous results (tried to teach me how to drive way before I was ready - an expensive lesson for her), other times positively (got me to cut my hair when I was 10, which got me thinking about how my personal style might be different from what my mother imposed on me), but as I've gotten older and started to understand how loaded her agenda really was, it's hard to look back at those experiences positively.
Now that I'm a little older and scoping out my personality and my boundaries (and how to push them in a non-overwhelming manner), I don't see myself tolerating a lot of this in the future. It's still hard to tell the difference between when I might genuinely need a push and when someone else is projecting their ideas about who I should be onto me.
Has anyone else dealt with people like this in their lives? How have you reacted/responded to it? I'm curious.
