the duty of grocery shopping

I go grocery shopping, I have my routine, I do things a certain way, I go at a certain pace, and let me tell you.... After taking my son along today, my routine does not include a 2nd person!!!! On my heels. Bitching because I'm walking too fast, or because I keep stopping. Yep, grocery shopping is a one-person job.. mine... Just me.... It's been a long time since he has gone shopping with me... And after today... It was be another long time until it happens again!!!!!!
