I've Swept in and Solved Eveyone's Problems

Alison and I are in Atlanta visiting my family and our friends. Since we got here two days ago we've repaired the following:

• My dad's wireless network.
  
• My dad's clock.
• My mother's new flat-panel TV.
• My mother's kitchen dimmer switch.

I can't help but feel that I've swept into town and solved everyone's problems. The experience has given me a heady but likely inaccurate confidence in my own technical problem-solving abilities. I'll probably try to fix someone's car before the weekend is out. That won't go well.
