If these normal frum teenagers are holding at a frum level still boruch Hashem then they should still be in Mesivta/ high school with a full day schedule which includes secular studies and sports also with your friends besides for hebrew first.
AND YOU KNOW WHAT? if the teenager is not on this regular frum level anymore C”V then these places I mentioned above opened almost 24-7 including shabbos with programs, food and mentors all completely free paid for by community sponsors. ARE FOR KIDS AT RISK ON ALL LEVELS not only at a certain level and they are loved by their mentor and Rabbi who runs these houses in each community.
If you are a regular mesivta boy and need some kosher fun and entertainment (mesivta high school actually is a pretty busy day going until late at night) then ask a classmate to join you for some fun ices to Rita’s or a game in basketball etc….
