I have 2 teenagers -14dd and 17ds. When they were younger I worked hard to make sure that they had nice table manners- used a knife and fork properly, cut up food properly etc. When they were on play dates people used to make comments about how polite they were and how nicely they ate. Fast forward to now and I feel like I’ve got 2 strangers in the house. Dd puts her knife in her mouth all the time and my son refuses to use a knife. They also used to speak nicely but both have got really really sloppy about how they speak. It really makes me wonder why I made such an effort to instil manners when both have them have regressed.
