My parenting style may look pretty chilled and carefree it but the way that I interact with my twelve year old son, Louis, is actually thought out very carefully. For example, if he tells me a rude joke I often laugh my socks off. I'll only comment negatively if I find his material offensive or inappropriate. It sometimes is as playground censorship isn't all it should be.
What my liberal stance means is that lines of communication are kept open. At times he's shared some pretty difficult stuff which I've then been able to deal with in an appropriate adult way. I'm not sure he would be so open if I told him off every time his humour was a bit lewd. After all I'm not as green as they come. He won't stop being smutty at my behest. It would just be kept under the parental radar. It's best that I know what's going on.
Anyway I'm up for a good bum, fart or willy joke myself. This is one of the titbits that Louis shared the other day. It's a bit rude and yes, childish but dead funny.
