My FI is a workaholic! He works for a big consulting firm so on top of normal work he is very involved in internal-firm activities like community service and firm events. This past weekend, FI woke me up very early in the morning (we live together). He couldn't fall back asleep bc he said he woke up and started thinking about this new project he was on and wanted to talk about it. UGH - I was grumpy all morning bc he woke me up. LOL
I am guilty of it too sometimes though...I check my blackberry when I get home from work to see if I might need to crank up the laptop at night...it's just the nature of my job. Most of the time I don't work at night but once or so a week I stay up late.
