DEAR MISS MANNERS: I am done with shopping for my older nieces and nephews for Christmas. They rip open their gifts, but never acknowledge the giver or offer any thanks, not even when I hand the gift to them outright. I watch my nieces open their gifts then sit and compare them to each other’s, all while ignoring me completely. They all have jobs, but still act like they are in elementary school when it comes to gifts: totally entitled. I know with giving gifts, it is the thought that counts, but my thoughts are that it’s time to stop.
