LW1, its all about setting boundaries. Years ago, I rented a condo from a 93 year-old landlady who lived next door. While not daily, I was regularly asked to help with this or that. I established that Wednesdays after work were set aside for taking my landlady grocery shopping, dinner out, and any heavy duty chores (a quick vacuum, take out trash). I included her in holiday dinners too, Thanksgiving, Christmas, Easter, etc. She'd treat too, regularly.

9 years later, she retired to a seniors' care facility. We agreed on a price for me to purchase the property. She made all the arrangements through her attorney including holding a note until I could refinance. When it came time for me to sign the papers, I learned that she cut our agreed purchase price in half! She gifted me half the property, worth low six figures. She never mentioned a word, her attorney assured me she was explicitly clear of her decision. Good deeds are rewards in of themselves; sometimes even much more so.
