^ I have to agree with this, even though I'd love to take me girl to a konzert, well, 'tis just not the same. You cannot headbang the same way as if you were alone, because you may hit your girl or she might acually get pissed of yer headbanging.
Also, you have the "glorious burden" of keeping her safe. Alas, I remember when Helloween came here for the 2nd time, I was with my girl and there was this huge guy hitting on her in the middle of the gig, and I had to watch the hole fickung konzert that he didn't do anything, so yeah, not much of seeing the band (the sound was terrible anyway). And actually me girl told me that the guy tried to kiss her once, but she hit him on the balls *claps*.
Fucking shit hehe, anyway it's definetly not the same, and you always end up loosing somehow, because if you are with yer girl @ the gig, you don't enjoy it 'cause ye have to watch her, but if you don't take her, you'd feel terrible for not taking her (hence not enjoying the konzert), or she'll make a big and unnecesary fuss about you not taking her, saying things like "Don't you love me anymore? Why oh why can't I be with you at the konzerts? Is it my body? It's my body right? I know I'm ugly but you don't have to do these kind of things to me! *cries**buuuaaaaa*"
