re: That last bit of toothpaste in the tube knows no end

I had a live-in GF in grad school that I gaslighted for an entire semester. She used to take pride in getting the last brush out of a tube. I got another tube of the same toothpaste and a large syringe and would put some into her tube every couple of days. EVERY morning and night she would talk about how much extra toothpaste she was able to get out of the tube. She figured it out right before Christmas and one morning she left early and I got up and found the tube and syringe on the bathroom counter and "frick YOU" written in lipstick on the mirror. I wrote back "Sure anytime" in toothpaste. No "ragrets" though enjoyed the angry sex.
