To go to church and Sunday brunch, of course!! What, you would just stroll into a house of God with an un-tucked T-shirt? I think we can all afford to tuck our T-shirts in when attending the worship service of our choosing. It is just the right thing to do. And if you don't respect you daddy enough to tuck your T-shirt in when he is springing for the Hometown Buffet, then you arn't a son to be proud of.Why would you tuck in a t-shirt?
