Ummmm....where did you go???

I was on a break at work and got on Facebook and saw that my husband was on there as well. After a little bit of chit chat I asked him if there was anything we needed for dinner that I needed to pick up at the store on the way home. He said "Let me go check". He then logged OFF of Facebook and has been logged off for 15 minutes now. Ummm....helloooooo??? Really? You lost focus on that task in 2 seconds??
