Ah dude it's only octane and the clones, you can easily get cheap replacements. We all make mistakes man! I'm sure your gf feels bad. I don't think throwing a tantrum over it is quite in the spirit of Christmas.

I've been in a very similar situation myself, but it's not till after everything is resolved that you realise how much of an ass you were. Hopefully you get them back in good order.

BTW, Id be cautious of that Octane. I think an ideal one would have at least some chromewear on the underside of the tanker cover.
