Popa – I am actually in agreement with you 😉 (remember all our good arguments in the past?)
But seriously, SLICHOSGENENDEL- what is wrong with someone locking their bedroom door? It’s their home and their business. Maybe they didn’t have time to clean up, maybe they were being cautious – yes frum people can be snoopy and look into people’s personal stuff. I’ve heard stories. Whatever their reason, it’s none of your business. It’s not weird at all! As someone else pointed out, be grateful that they let u use their home. I hope you brought them a gift to thank them.
