HALLO!

How much effort does it take to say hallo to me if I say hallo to you? When mummy takes me to nursery on the bus I greet the bus driver first, they always greet me back. Then I say hallo to the passengers, there are never very many at that time of the morning. It works like this, if i say hallo to someone and they say hallo back, we pretty much say hallo to each other for the entire journey.. repetition and all that. But sometimes I say hallo and they don't reply, they ignore me. So I say it a little bit louder because maybe they didn't hear me the first time... they ignore me again? So I shout, as loud as I can .. H-A-L-L-O!!!!! And guess what? They say hallo back. But I don't bother saying it again, not with those types anyway.
