I agree with everyone get a pet as long has you can financely meet his/her needs. Pets can be expensive and I don't want you to get something only to find out that the cost of up keep is to much.
If you are thinking of a cat which I do recommend go to your local animal shealter they have a lot of cats and other animals. Cats and dogs really like to cuddle which can get you through a long night.
My dad has a blue front amazon parrot. The bugger almost outlived my dad. The bird Jed died when he was 44 years old and he could talk and say naughty words and was a cranky old man.
Good luck on your search. You can look at pets from the shelter on your computer before going down there
