H is For ...
Hacker - Being a hacker is a good thing. In recent times, the word has been misused by the media, but it originally had only positive connotations. The basic difference is this: hackers build things, crackers break them.
Haiku - A form of poetry. I like haiku (and senryu, the variant most people are more familiar with.)
Hair - My hair is a medium auburn color and wavy (not curly). I like my hair. It kinks up in humid weather, which we had a lot of when I was living in Pennsylvania and Maryland. However, the weather in Northern California, where I live now, is perfect. My mother used to occasionally suggest I "do something about my hair". I don't think she had in mind my moving to California, but it worked.
Halibut - The "holy flatfish" (and tasty with butter sauce)
Harry Homeowner - When Rich and I are doing some sort of project for the house, we say we're channeling "Harry and Harriet Homeowner".  Rich will say "I'm going to be Harry for a while" or I'll say "I have a project for Harry".
Heater cats - We refer to our cats as the Heater Cats. The name comes from a sketch on Garrison Keillor's  "Prairie Home Companion". Heater A heater cat is a Big Warm cat, suitable for Minnesota winters. Buy a big coat with four pockets sewn into the inside of the front, then pop a heater cat into each pocket... At night, they keep you warm in bed. Heater cats are bed warmers, lap warmers, and life warmers.
Heffalump - Help Help, a horrible heffalump! A heffable horrilump!  If you don't know heffalumps (and woozles) you need to read more Winnie the Pooh stories.
Hickory Nuts - I love hickory nuts. They're shaped like a round pecan and have a flavor that's reminiscent of maple. My grandmother  used to bring hickory nuts when she'd come to visit.
HTRCATS - one of our license plates.
HTRCATZ - our other license plate.
Hummingbirds - we get these frequently in our back yard. I love to have a hummingbird hover a yard or so in front of me, cocking its head from side to side, trying to decide if I might be a flower.
Having said all that - H is also for Harmony, Heliocopter, Happenstance, Hedgerow, Habitat, Haemoglobin
