Oh definitely.* And really, even in 'adult life' it doesn't
   matter what you do 'til somebody complains about it.* Even THEN
   it doesn't really matter unless you're sent to court.* Then
   things cost money.* But working in business, I see businesses
   big and small 'get away with' lots of stuff.* usually the law is
   too confusing or difficult to comply with,* or they don't know,
   or they just don't feel like it, and some people follow the law
   to the T, and most are inbetween the two. But yeah - TM doesn't
   mean anything.* but the TM symbol does.* The only one I'd really
   worry about though, is INC.* That's a big no-no and people
   notice quickly.* But most of the others you see in businesses,
   anybody can use.* INC is a big no no and ... LLC.. yeah that's
   the other.* I'm not sure about Corp or Corporation; they might
   be ok, as it's the INC that matters, but maybe Corp/Corporation
   does too.* Not sure. But there's really only a few big no-nos
   but it's really surprising what's "ok".
