My children who live with me fulltime are 11 and 17 went to stay with their father and his G/F's family for easter. They both came home argueing with each other as usual and wanted their easter eggs from me and my fiance. We didnt even get a thankyou, then my son was bragging about how he had spent $60 on easter for all of them so then i said 'jokingly oh so then where's mine'? He then says 'oh i didnt get you one'. I didnt even realy want an egg and i never expect them to buy me anything but usually they give me a little egg out of what they have been given seeing as they get a double lot off eggs being from a split family. My son has only been living back with me for 5 months and i do all the running around for him and clean up after him and not to mention getting up at 5am so that he can get 30mins driving lesson in before he goes to work and again in the arvo for another lesson. I am annoyed at the fact that he thought about all of them and not us, they who do nothing for him and he has spent the last few months telling me how much he dislikes them because of the way they treat him and we dont even get a thankyou. I just dont know what to say to him or even if i should. Would you be feeling the same way or am i over reacting and what would you say to him.
