NC with mom she sent a birthday card. Return to sender? Trash and ignore?

Hello!

For context I went NC with my mom for the final time. Check out my other posts for tea at my own expense.

My birthday is Wednesday and according to the USPS mail notification email, she sent me a birthday card with a $25 check. (Im assuming a check is included she always gives one but I never cash it because shes always been "poor." Which for context on the quotes I found out three weeks ago shes been hiding $250k, taking hand outs from churches, food banks, etc. This context might not be important).

Anyway, I've seen other NC women returning gifts for their children back to sender. Or others are just ignoring it.

But my concern is shed make a big deal about me "cashing the check and not saying thank you," to my siblings and it becoming a whole. But she also hasnt noticed me not cashing it for at least a decade. (As I type this part, I should probably unpack this re my siblings in therapy).

Im not sure what to do. But everything feels like the wrong choice.

What has worked for you?
