People just don't say thank you like it was done in the past.I gifted two family members a lot of items for Xmas.Never told me if they received it until I asked, then one said thank you.The other person never said thank you. That's fine.I will do less next time. When I got married, my husband & I mailed out or Thank you's as soon as we got back from our honeymoon. And I always say thank you to everyone.Especially when I am helped or rung up by young black men, I go out of my way to say it.
