I totally agree with you bud.. Although giving should always be a selfless act which means GIVE and don't expect! Also not expecting is against the nature of humans but if someone excels this art.. He/she will gradually be in the happy zone.. Spreading joy and positivity around!
Telling about the food which we love is always something that we crave for and when someone is full.. He doesn't actually crave for Food ;) what's say?
Looking at anything with a positive attitude will give you answer to all your questions and plus you get Happiness in the form of bliss :)
