My son has recently began saying odd things at odd times. Like while carrying something to the garage he said "I could dump these on your head." I said "why would you do that." "because it would be fun" he says. I said it won't be much fun and he replied b/c I would get a spanking." Anyway he was in trouble for something earlier in the day and he told me he was going to give me a spanking. Anyway I was wondering if I should punish for these things or just ignore them.
