My sister in law didn't bring a gift

Hey, so I know this is going to sound so incredibly selfish and ungrateful, but I have 2 sisters in law, Michelle and Violet. Violet went above and beyond for me, hosting my shower, giving me gifts prior to the shower, buying my most expensive registry item for me (seriously the best sis I could ask for!) I'm planning to give her flowers, free babysitting, and a generous gift card so her and her hubby can have a really fancy dinner as a thank you.

Now Michelle and I get along really well. I've helped her take care of her kids and we have awesome conversations. I even hosted her baby shower! She feels like a really good friend of mine. I was a little taken aback that she didn't give me anything for my shower except for some strange hand me downs (like a used candle, some pee stained or damaged boy onesies (I'm having a girl), and some other hand me downs that are so worn out from four previous owners). She is not a materialistic person, but she definitely is well to do financially.

It just irks me and I feel confused, thinking we are so close and she didn't even get me a card while my other sis in law was shockingly generous. Is that weird?

I know I should just be grateful she came to my shower, which I am! I even had some great conversations with her after opening presents. It was just when I got home I was just like okayyy should I be offended at all?
