Son could smell, heck, he doesn't even have a 2DS, get with the program kiddo! I wouldn't want a kid without a decent Nintendo handheld either if I'm honest.
Better put a joke mark, some people may think you are serious =p
If someone was to think the comment was serious, what would the issue be? Someone who can't see a joke getting offended for a smelly child made up and disrespected in the same single line post? If they start a gofundme page for said child I think I would be the only beneficiary of the funds, as the unwanted smell child's creator!
Shit I think at this stage 50% of every post I make on this site is in some way intended to be at least light hearted and slightly humour based, I'm 36 imo that's too old to be getting serious or bent out of shape by most things online. Unless someone replies and just calls me a c**t or w/e, that gets old fast.
