A friend still kisses her 14 year-old grandson on the lips
An old friend of mine is raising her adopted daughter's son as her own. I've witnessed them being overtly affectionate and it bothers me. She tells him she loves him very frequently, and she kisses him on the lips. When they sit, they sit together and often put their legs on top of each other's as a couple might. It makes me very uncomfortable, and I'm concerned about what might be going on when they're alone in the home. Is this behavior normal, or a sign of something that I should alert the authorities about? They're not related by blood, but he is underage.
