Actually, two things:
1. that is well within PG, let alone PG-13, rating.
2. you might be surprised that more than half the time I get done writing a post and then stop and go somewhere else without posting it. Then, some time later, I come back and realise I haven't posted it, or will remember I haven't posted it and do so. Sometimes, I'll think back wondering if I remembered to press submit - cos some forums I frequent I have 'preview post' set.
