How to track a straying spouse

I've never liked going out with women. I cant stand their conversation at all. I was having tea with hubby the other day and we were seated right behind a table of women. Most of them in their late thirties, or maybe their early forties. 95% of their conversation involves trips to the beauty salons, shopping and about their straying spouses. The other 5%, i cant understand. Cos they were speaking in a different dialect. I dont mean to eavesdrop, but how not to. They were rather loud and i'm just right behind. So, the blogger in me kept my ears opened. What to do? A blogger gotta do what a blogger gotta do, right.

I'm not interested about the shopping and beauty part. I'm only interested in their straying spouses, lol. One of them mentioned about the high cost of hiring a private investigator to check on her husband's whereabouts. Another one mentioned how she installed a gps tracking device to the bottom of her hubby's car to check where he goes each day. Wuah.... innovative, eh. Men, you scared yet? See how high-tech women are these days. If you are planning to cheat on your wife, you'd better go check your car properly for suspicious devices. Now, ladies. This is quite a good idea, eh.
