@MagikaalSorry for the delay, i need a little rest and a break
So now I asked (in general) what kind of gift you could do to J that could please him
Bear/Cross/Dog
I suppose a gift that would have the following characteristics:
1) Bear: put it to the test, allow it to use its strength or will, control, Be assertive
2) something which is not too easy and which brings him some obstacles, difficulty that is not so easy to solve, a challenge, which allows him to surpass himself (Bear / Cross)
3) A game that he could share or play with a friend or family
Does that give you an idea?
Now for you proposition I pulled a card for each:
1) Birds : I think he could be very excited by this gift which would allow him in addition to discussing, communicating ...
2) Scythe : No. It seems that you can forget this one..
3) Book/Moon (jumped together) : ok it seems this one could be have success if it is a book and a really good book as one which have had a success or which has been designated as a really good magic trick book for youth.
Now if I look at the answer and the proposals you give, my choice would be for a set of legos that offers a difficulty and that is not built too fast. Maybe something that would allow him to start a kind of small collection to play with his siblings?
The legos offer a lot of very interesting thematic, which requires precision, reflection, meticulousness and which once built offers a very good support of imagination's games and gives a feeling of pride (to show to others what he has succeeded despite difficulty and because of his will) .. Bear is very proud, Cross asks the question to succeed or not because it is difficult so I will choose this. As he is 12 years old, he is no longer a little boy, looking for a set that corresponds to his age especially.
Hoping this helps you
One question might be: what would be the best goal for me to have this year? (The one I can succeed)
Otherwise you can read for me something you want to try because I like your proposals
You can always ask if you need
