Yes, someone is reminding us about the utility of having a few Mason jars handy for storing jams and jellies and also maybe some pickled things. However, all these canning jokes distract attention from the fact that actually I am not the Mason jar to whom you refer and cannot imagine why we need to talk about that. I am sure that there is a place for Masons somewhere in society but anyway I really am not sure to whom I should be redirecting these Mason jar commentaries. I really had no idea, but that is interesting to know. Ball jars are another brand name that I can remember.
