What is the origin of the phrase “I’ll hold up my end”? [3351C]
If you’re carrying a heavy load with another person (e.g., a sofa), each of you is likely to be holding one end of the load, which can’t be carried by one alone. To AP, holding up your end can be extrapolated to doing your part on any project, not being a slacker and not trying to get away with having others do all the work.
