To be completely honest Archie hadn't been attempting any sort of cheek or humour with his blunt answer, nor of course was he trying to be rude. He had genuinely assumed that his mother was curious about what he was up to right there and then for he hadn't thought about his future and didn't think that he was really meant to have done so at this point in his life. He was still young after all and frankly was quite content living in the moment even if that moment was as dull as lying down and doing nothing.
His mother would explain her point a little bit more, there was no way at all for Archie to misinterpret it this time though he preferred his previous assumption to this one. This was supposed to be serious matter he sensed though not one he really felt like dealing with nor one that he really thought was all that important at all. He'd be good at whatever he did after all, he was an Armada and had been raised by two talented parents. "Do I have to?" He enquired, the look on his face clearly not too impressed by the topic.
