I don't know if it's a me thing, a guy thing, a person thing, or if I'm the only one.
I HATE making two trips. If I'm taking my dinner out to the living room to watch TV I'll carry the plate, a drink, napkin under my chin, balance my plate on a bowl and whatever else it takes to make a single trip. It literally takes 20 seconds to go from my living room to the kitchen and back again but I'll risk injury and a huge mess. So weird.
You don't even want to know about carrying in groceries from the car.
