Well as i have a tatoo on my face i very much doubt that i will get anywhere with the no tats or piercing route, wouldnt want to really, i love them. (poor middle class father on the other hand had just that plan for me....didnt work)
Im also Tory so would hope i dont turn out sappy liberal kids 
Also bikers, alothough taking a few years off while they are very small.
DH is from a military family...i will be (already do) show my complete disdain for a career in the forces. (sorry but it is partly from witnessing my DH's military family, not pulled out my arse!)
So for me i would gutted, truely gutted and feel a bit of a faliure if my children joined either the forces or religion. Gutted! However, if it really was what they wanted to do then i would do my utmost to hold it together and be supportive.
