Not everyone - Christmas trees have always been real ones in my family. If you don't live near where pines grow you can get a nice Christmas tree from a she oak.

The primary factor is that 120mm is not the actual focal length of the lens in the phone, that will be a considerably smaller focal length that happens to give the same field of view as a 120mm lens on a full frame camera (i.e. the same sensor size as a 35mm film frame). The phone uses a much smaller sensor than this hence the smaller focal length for the same FoV.
Another thing that helps is using a telephoto lens design - including this lets you create a lens noticeably shorter than its focal length.
When the lens would still make an overly wide phone despite all this that's where the periscope lens design as others have already mentioned comes in.
No, I'd need to think about it. I don't have a pre-chosen opposite gendered name (it's not something I've thought I needed to consider) and my name is not one that can be easily adapted so the easy option is out.
