Covid

Hey guys covid question. I’ve been extremely careful of covid bc my dad is really high risk. Seeing my boyfriend over the year has been difficult bc I choose not to see him if he’s been w friends, etc. For the past month his family literally hasn’t left the house except the brother two days ago. He went to LA (his college is there) to only pick up his books for his class (apparently the library was closed and they had a drive thru where they gave u ur books through ur car window). Afterwards he went to his apartment in LA and stayed there, only ordering doordash for lunch and dinner. Other than that, hasn’t left his house and is coming back tmrw. I know how bad covid is in LA, but is what he did pretty safe since he didn’t hang out w ANYONE. Please let me know what you guys think.
