Crawl after him as fast as I could and snap at him with my 'beak'. Actually, turtles make bad fighters, I'd probably just be kicked away.
Sneak in after him and seek out my fam AEAP. They'd be able to throw out an old man. Find a way to communicate with them (with the kind of biscuits formed as letters, or similar, even use paint or my own blood to write a message) so they would know what had happened and who I am.
Maybe I'd wish to stay a turtle.

Since i was turned to a crow, i would stealthily enter in the middle of the night, try to find the recovery potion, or if i don't find it, stand next to him in the bed while he's asleep, make a crow noise, when he wakes up, pluck out one of his eyes, leave whrithing in pain and make him give me the potion, after that, probably call the police.

Ok, so there you are, walking down the street, when for some reason you look up to the night sky, and then see a tall and big house, the house is kind of dark in a sense, but also mesmerizing and beautiful, for some reason you just want to enter there, as you see the full moon shine through the windows of the tallest room with some crows suddenly flying out that section, you notice that it seems to be abandoned and it's opened, you know you probably shouldn't go there, that it's a bad idea, but you just can't avoid it, the place just hipnotizes you, as you enter a bit through the door, you hear close to you (but you can't see it) a little girl crying, not crying in a "i want my mommy and i'm totally not a monster that's gonna rip your soul of your spine" but she just asks for anyone, in sobbings of pure sadness, you really feel that you wanna go with her, due to how sad and scared she sounds.

What do you do?

I start to get a really bad feeling, the adrenalin is kicking in and my heart is doubling in speed.
My brain starts to imagine all the horrible things that could have happened and then before I
know it my legs start moving, and I'm picking up pace. Before I have time to think about what's
happened I'm back on the driveway of this house with the girl in my arms. I place her back on her feet
gently and kneel down beside her to ask her what's wrong. A shaft of light breaks threw from the
tree line illuminating the girl, I see her thin arms reaching up to her face, small hands clawing at
empty eye sockets!

RAHHH!!

XD

you've ordered a pizza and the delivery boy is now at the door waiting for you to pay. you open your wallet to find that your money you had a few hours ago is now gone. what do you do?

First I'd grab my gat. Not to use it - just because I always take my gat with me when I answer the door. Then I would go to the door and explain the situation and ask if I could get the pizza on spot or something. If not - meh.
