Looking at the first post, it's been 3 months and two days since this experience started.
Last week I was back in Portugal for the Easter break and managed to clean up the things I had in my parents house. Half of them were there since I moved to Norway, about 2 years ago, but the rest was there since I moved out... about 5 years ago. Concluding, I threw away 95% of it, recovered 2 hats, a summer skirt and summer trousers and I brought my party pochete and echarpe (the dresses were already here). All the rest is gone. Finally!
Unfortunately I still have work to do in the Summer visit: I did not have time to clean up the things at Filipe's mother house - a lot of CDs and DVDs that we need to sell, some sentimental decorations that we kept when we moved here, and some previous work notes/documents/copies that need to disappear.
The house here still looks good and tidy, but because of the trip, there will be some maintenance work to be done this weekend, from cleaning to re-organising the extra groceries that we brought from home :)
