Whilst in the middle of chatting with a girlfriend, and making breakfast, my telephone rang. From the number it was a client and friend whose problems were of an urgent nature. Interrupting both my activities with a polite "I'm sorry I have to take this." I answered the phone. This is the problem with the Other Job. Its not a set schedule of hours. It just pops up in the middle of the rest of life and expects to be dealt with NOW.
There was this one associate I worked with who ONLY called when I was up to my arm pits in a project. Once, he interupted himself to ask, "did I catch you in the middle of anything?"
"Yes," I responded. "I was making bread." At least he understood when I showed up at his office with flour in my hair.
Another associate only seemed to phone when I was in the middle of changing diapers. After almost dropping my phone into the poopy side of a big mess, I gave up answering, and just started returning his calls thirty seconds later. It is actually a good strategy for keeping the Other Job seperate. I love caller ID for the same reason. If there are screaming children in the background, I'm not about to answer a work call. Family will understand.
Of course, small children and phones have an ongoing competition. If all is quiet and you answer the phone, you only have five minutes to complete your business before someone screams, hurts themselves or demands loudly that you get them more to drink. Seriously. Ask any stay at home mom, even those who don't have another job on the side. It could be 2 AM, and the wee ones asleep for hours, and they will still pop up while you are talking on the phone.
At least my girlfriend runs her own business as well. She just laughed and said, "I'm glad to see I'm not the only one."
