Within the cosy embrace of the G.6.6, where many hours have passed by, strong friendship bonds have also been established. We have all laughed, argued, cursed and shot each other but, above all, we have been really good friends. Thank you all that have been part of this journey and, in particular, thank you João Gonçalves, Tiago Cruz and Vítor Bernardo, without you the outcome would not have been the same.Last, but most definitely not least. In all those moments where I was grumpy, harsh, defeated and boring. When I was working at night, weekends and holidays. Every time I needed an "expression check" and revisions.Thank you for being unconditionally by my side, you have played a Stellar role in my life.
