I kind of get it for children - especially ones you don't make an effort to see know very well - who may have a particular interest etc, but otherwise these isn't the practice of asking others for "ideas" (i.e. asking them to choose) pretty annoying? It's difficult thinking of ideas for presents for people sure, but thats half the job, and I am finding it so irritating to be expected to carry the mental load of doing this particular part of present given for my entire family every time Christmas or a birthday comes around.
(My post is triggered by the annual texts from DH's family members 3 days before his birthday asking what they should get him. I struggle enough thinking of something to give him myself, don't put it on me to choose what you give him too)
