Giving and expecting reciprocity is NOT giving, but rather an attitude of mercantile exchange where one offers something and expects something in return (gratitude, praise or respect, etc.)!
You will always be disappointed when you demand gratitude and respect.
Those things must be earned.
When you learn to give with a grateful heart without strings attached, you will be rewarded in infinity.
If you cannot, then you will forever be disappointed or living with unrealistic expectations.
