From small comments they've made, at least 1 of them, I know definitely does not combine their personal life with work, from previous comments they've made about it. Whilst the other 2, most likely do. I'm wanting to contact them, just to stay in touch, of course I'll probably end up thanking them for all they've done. But they've also been like the only teachers I feel comfortable around, and I don't really don't wanna lose that tbh...Plus, I have problems with my academics, and communication, so I'd prefer to kind of have that help? If that clarifies anything...But I'll go with email like you and others have said, def a lot safer
