I don't blame my parents, they were oblivious to what they were doing with this, but....
Growing up, we'd always go out to 'celebrate' birthdays and special events (typically at the Brown Derby), and on the flipside we kids were kept at the table until we 'cleared our plate'. As such I've been wired to ALWAYS finish my plate, and whatever my kids didn't finish. This is buttressed by growing to hate leftovers, so yeah, eat it all at first sitting.
This means I historically ate everything in sight so as not to leave food. It also means that I associated eating out with happiness, and as I grew up, went away to college, and generally learned to live as an adult I would eat out a LOT more than I ate at home. Part of this was because life was stressful and eating out and/or eating sugary junk food was a means of coping. Part of this was living on my own, earning a paycheck, and talking myself into believing that "I can afford to live nicer by eating out" with all those paychecks.
The result is being overweight since my early 30's, diagnosed with diabetes in mid-30's. Mentally I believe I can control what I eat and get things under control. The last 25y say the reality calls me a liar. I can barely boil eggs, never developed my cooking skills. And, my kids have watched me be this eat-out personality and have picked that up. My oldest rarely eats anything from home, 95% drive thru or eating out. My younger one asks me at nearly every meal "You eating that because you're hungry, or because you can't say no?"
