I'm not making any assumptions at all. I accept that it's going to be up to chance. Either they'll like it or they won't - if you have no information, guessing at their preferences is pointless.
Steering clear of common triggers is an attempt to maximize the chance of the recip enjoying it. Beyond that, in the absence of any stated likes or preferences from the recip, there's nothing the author can do so they might as well write something they (the author) enjoys so there's at least one person who's guaranteed to be happy with it.
