I don’t see it that way at all. The two wanted to sit together, the daughter subconsciously needed to mirror her mother, so she did. It doesn’t say anything about my relationship with friends I used to hang out with, that I smoked cigarettes with “socially”. I never asked them if I could not smoke, they never pressured me to smoke in any way. I simply had an instinct to do what they were doing. I felt more comfortable that way. I’ve dated women who hated beer but when surrounded by people drinking beer, they would drink half of one. I think this kind of thing is extremely common. Peer pressure isn’t always overt, as in someone suggesting someone do something others are doing.
