Just how busy is my husband at work?

I have often wondered why my husband doesn't immediately reply to my emails that I send him. I wonder if he is really busy or just telling me that to avoid a long email conversation. I decided that I am going to measure the amount of sent emails from my work email account vs. my husbands work email account for the month of January 2009.

My data

Number of Emails sent in the Month of January

Attached is a copy of the assignment which indicates a semi-positive association, but most of the results fell on the zero line. The correlation is not strong and seems very scattered. I think that the lurking variables that could have been present is the number of days that my husband and I worked at the same time. My husband also has to work one weekend a month, which would give me a better advantage of sending more emails than me. I think that seeing this data helped me understand that my husband is very busy at work (sometimes) and perhaps I should stop requiring time from him when we are at work.
