Don't want to tell anyone how to parent, but having grown up the youngest of 5 brothers (including myself), I would say it's more about how you're socially raised than any gift giving. A young child can pick up on resentment at ages you might not expect, and resenting them for not appreciating gifts may exacerbate deeper issues, such as feeling like they're not the favorite child. You more than blatantly said so yourself. The bottom line is, you can't buy respect or love, even from a child.
At the same time, social spoiling I feel is far more of a problem than material spoiling. when I was like 10 I realized one day my older brothers, who were teens and old enough to know better, were doing things they really shouldn't have been, When I mentioned it to my parents (which at that point included a step mom), they just laughed. Older siblings are often given privileges younger ones aren't, and when they are also given more lenience, that's where the resentment really starts.
OK, now for my personal Monkey moments. I finally found out the reason my car wasn't going into EV mode anymore was my 12V battery was pretty much shot. It got to the point where 2 days after doing my freeway loop that the thing was already showing a red sensor icon on the dash. At first I thought it was just that I'd accidentally left my headlight switch slightly toward the parking light mode when I parked one time, but O'Reilly tested it to be too dead to take a charge.
I ended up getting a better than OEM spec one for the vehicle, which has about 700 CCA vs the OEM 590. It's an Optima Red Top, and they gave me a discount on it so it wasn't more than about $30 higher than their top end house brand. Immediately after installing it, my car then went into EV mode like it's supposed to. I figure the saved gas over time will more than pay for the higher price.
Another thing I just had to purchase is an umbrella. We get a fair bit of rain here, but where I live the wind can also swirl unexpectedly. I had a big pop up one for years called a Big Top model, it had a 48" diameter canopy, and sturdy hex shaped steel shaft. I must have had it for like 20 yrs. Yesterday while walking to the bus the wind swirled hard and yanked it sideways a bit and turned it inside out. I didn't notice until I got home that one of the canopy frame ribs had a broken joint.
So I just ordered a Repel Travel Umbrella on Amazon. It's a double canopy type, so theoretically the wind can blow through it, but I'm a bit skeptical, because where those dual canopy layers overlap at the ribs, the wind can also catch there. It DOES however use reinforced fiberglass on the frame, and thin, flexible rib tips. It also comes with lifetime replacements. You basically send them a pic of the broken part and they send a new one. It's got a 4.5/5 rating with over 100,000 reviews.
