Ask them to please leave you alone. Do not give them food, cigarettes, phone numbers of food banks/drug rehab centers/social services. If you wish to pray for them of course go ahead but do not inform them of this fact. Under no circumstances allow them to come into your apartment.
If they do not respect your polite request to be left alone, the next time they bother you, contact the authorities. These people are streetwise, they do not need your help or advice. They are very sophisticated at survival this way.
And by the way, if they are using drugs, they are neither ârecoveringâ nor ârecoveredâ addicts. They are just plain and simple addicts.
