S1 is a rising senior (college) and my wife sends him care packages about once every other week (he is in Ca and we in the Midwest). I have calculated that she has spent almost $1000 on usps priority shipping alone in the past 3 years. S has worked a research fellowship every summer so we only see him for 3-4 weeks in August/September and over Christmas break. My wife occasionally mentions that it seems S doesn't appreciate it (i think he does just doesn't say it). I told her to stop sending them if she feels that way. But I know she won't, I think it makes her feel a little closer to him to take the time to assemble the items and pack and ship them (she often shows me how much she can pack into one small usps box).
Is my wife the only one that does this or is it a common practice?
(I have a feeling it tapers off after first few months in college.)
