Ain't it the truth. I got married two weeks out of college and worked an 'entry level' job and a second part-time as I finished up my bachelors at university. Money was a bit tight. Squirrel: it's what's for dinner. We have a semi-enclosed back porch where we would dry sunflower heads, and any squirrel found on the premises was apt to get a lecture from Brother Benjamin de Pistol and be invited to supper the following night - regardless of the season.
I don't drive $200 pick-ups anymore, but I still keep my hand in at squirrel hunting. I just take a lot fewer shots. Raised geese & rabbits, but I never did get used to hand-killing the rabbits. I much prefer shooting them. I don't think my wife, a school teacher, misses her 100 x 100 ft 'garden' much, either. We used to raise/shoot/catch about 90% of our own food.
Anyway, I had a T/C Seneca in .36 that was a joy to squirrel hunt with. Fool that I am, it is one of the former firearms that I wish I had kept. Never owned a .32 M/L, but I imagine it would be ideal for tree rats. In truth, my preferred weapon in the 'old' days was a pump .22. I have a Model 12 Remington (Grandpa's) and a M92 Rossi. The Seneca came in late in the war, but was my preferred method until I got into my traditional archery kick (last 15 years or so). After that, killing squirrels using ANYTHING with a trigger seems relatively easy. You just gotta wait the shot out.
