He might be trying to be a shining armour knight for the WL he has fallen in love with

Or

She dumped his sorry ass & blocked his LINE, Webchat, WhatsApp, Facebook, Calls & Text Messages because he follows her to different shops & she hates him

Either way, he has a valid point. At the end of the day, we are all at risk

WL can sleep with 12 guys in one 12 hour shift
If she works 3 shifts, it's 36 guys a week
Over a year, that can be more than 1800

Now that's a reality for a WL...And the risk we take
