By 18 january 2016, member states shall notify to
the commission the list of professions for which a prior
check of qualifications is necessary under article 7(4).

sometimes i get confused when it comes to "by" and a date..
does this mean that "the member states shall notify to the commission the list before 18 january 2016", or "starting from 18 january 2016", like, "after 18 january 2016"? in advance..

Ineed advice. i have a lot of friends at school but recently my best friend for some reason didn’t like our friend group. she wanted to switch to a new table during lunch. she said she found a new table where we would be welcomed if i wanted to come. i agreed because i knew i would continue to talk to them outside of lunch. after a month or two, my best friend got mad at our new lunch table group. so she left for a day or two, but i stayed because i actually kinda liked it there, even if it was kinda crazy. then she came back to the table. eventually i started to miss my old friends at my old lunch table. so i went over there for one lunch. then after lunch i sat at my new lunch spot before the bell rang. they all called me a traitor. so now i sit with my old lunch group, which is fine because i missed them, but i also miss my new, now old, lunch table. what should i do? p.s. sorry if you loose your last brain cells trying to understand this.
