Do you all think Hagrid led the rest of his life (after the war) completely alone? Is there a chance he had a family?Well, I hopw things with Madam Maxime worked out in the end and they were together, at least once she left the Head Mistress job, or something. I don't think they could have kids, not only because of their kind, but because of the age, since Hagrid was ... how much did I say? Like 80 years old ...
Do you think Harry, Ron and Hermione remained close with Hagrid. After they left school and had families of their own?Yes, definitely, and you can spot that in the Epilogue, when Harry reminds Albus about going to have tea with Hagrid next Friday. I think the Trio owes a lot to Hagrid, and they think about him like ther best adult friend, so they won't just leave him, forgotten. Of course once off Hogwarts the opportunities to meet him and all would be less, but they definitely remained the closest.
Describe why you like or dislike Hagrid...this should be interesting!What I like about Hagrid:He's got a great will, to carry on, despite he sometimes broke out, like when nasty Skeeter discovered about his mother; he could carry on. Also, I love his huge, marvelous loyalty: he never betrayed the people he was loyal to, he never betrayed himself either; he never tried to be somebody he wasn't. Then, that he was kind to everybody, great with both the new and old students, and he tried to follow Dumbledore's example and give a chance to every one, but he couldn't, yet fought for what he believed for. Oh, and I love his love and respect for every being.
What I dislike about Hagrid:Um... that you can't trust him anything, that of course

It's a complete disaster! And the fact that he believes what is good for him, is good for everybody, and so exposes people to the crazy cratures he loves (and me too! but I wouldn't force you get too close to a Blast-Ended Skrewt).
