wow that is a hard question. because i thought about it as if i had just caught my nephew... :wtf:

i would probably talk to him about it first but still tell my sister, because she should know what her son is doing.

so yea, i would say talk to him first then tell your brother about it, well actually, i dunno because how does your brother feel about smokin? that would be part of it. you dont wanna throw your nephew under the bus, but its the right thing to do.

hmmm, a much harder question then i imagined. i dunno i guess its all on you because we dunno your family members
