Neighborhood bike pump
Be weary of letting the neighborhood kids know that you own a bike pump - cause if you do, you may unleash a fury of unknown kids ringing your doorbell asking for it. This was the situation I found myself in a few months ago.
Over the course of the past 2 and 1/2 years living this new subdivision I have befriended the 2 boys across the street. And when their dad ran over their bike pump (left in the drive way) with the car and broke it, they came to me asking if I owned a pump - which I do. From that moment on I was getting my bike pump used 3-5 times a week by numerous kids for about 6 six weeks.
It's a somewhat weird deal to have kids that you never have spoken to coming up to you asking you to use your pump - all needy - and knowing that you have it.
