As someone who likes to share with friends and family, I'm amazed by people's manners, or lack thereof. I feel that saying thank you, even when something seems expected, should be second nature, but the older I get, the more I realize that not everyone feels the same way. But is there anything you can do or say when your generosity isn't appreciated or acknowledged? I bite my tongue whenever someone "forgets" to say thank you, but sometimes I feel like I shouldn't. I might be overly sensitive on this topic, but ladies, do tell: How do you react when someone forgets their pleases and thank yous?
