Fall in Seattle

In this weekend i felt for the first time how fall is in Seattle. So far it's been very changing weather, but this weekend the leaves fell of the trees forming huge piles, and for me this indicates that it is really fall now. I went outside with the 2 boys in the family to rake up the leaves and play in them and play in their backyard. We had a very fun afternoon, and i really like spending time with these 2 boys. They've become some of the closest they can to my real brothers in denmark. Weekend is over now and school has started, i still enjoy it, but it's at the same time frightening and exciting that there's so little time left before we head home. Better put some good use to the  last weeks aswell. 

Uhm.. And i've been wondering about 2 things.

A couple of us went to a mexican restaurant in our lunch break at school, and we've gotten a little confused over if we should pay a tip or not. The thing is, that we enter the restaurant, and make our order at the front desk, and pay at the same time. After that we get a glass where we can fill pop in and go down sit at our table. After short time, we'll have our meal served, and when we're all done we leave, and they come and pickup the plates. So, we get some kind of service, but at the same time not full? Is it disrespectful not to pay a tip in this situation, or is it okay?

Another thing is more of a technical / matter of danish law and taxes.

I've been thinking about buying a new computer over here. At the  moment i'm just confirming that i'm able to get a danish keyboard in it, aswell as buy an insurance for it. These 2 things seems to be rather easy.

And for the model i intend buying, it's literally half price buying it in the US rather than in Denmark.

I dunno if you would be able to answer this, but i thought you might since you've been traveling quite a few times between the US and Denmark. If i buy the computer over here, and take it to use before i go home, will i be asked to pay the taxes (told) on the computer. It's a device i bought over here, but it's been taken to use before i enter Denmark? It's a little confusing, and i've also gotten my father to try investigate it.
