I suspect most people who have either not been a single parent or known one closely really don't understand just how appreciated the occasional "helping hand" can be. When you're raising a kid/kids alone, you are "on duty" 24 hours a day, 7 days a week, 52 weeks a year. Good on you for helping your friend out. Seriously, sometimes just having a couple of "I'm Free" hours is such a relief - even though in the back of your head you are never completely disengaged.
And yeah, I bet it was something at the Uni! When I drove the Daughter to the airport a couple of years ago to fly to Uni in Scotland, we'd never been apart more than a couple of days. She looked so grown up, and sooooo excited when she waved goodbye at me after she got through security. I stayed out in the parking lot (couldn't go with her past security) until I saw her plane take off. Then I almost had a wreck going home from turning into the offramp on the freeway (recovered quickly!) and cried like a baby all the way home.
She came back home again, though, and decided she doesn't like living in Uni housing.

I wonder why? Might have been the gaggle of roomates, including the Chinese guy who kept leaving fish guts in the sink and on the counters.... not quite like living at home. (thankfully)
