X-mas gift from a Nerd to his Wife (en/de)

How creative could a nerd be when it comes to a suitable, personal, romantic but not exaggerated Christmas present for his relationship partner..? Without wanting to be invaluable, but everyone (nerd) has to answer for themselves. Or just the gifted partner. At some point in a relationship, however, you might come to the place where you decide together not to make mutual gifts. Maybe because you just got kids. “Dear All for the kids!” Phew, super. Fine. Problem solved…
