Before I was married, I had a job laining in a shul that was a 45 minute walk away from my house. A family in the neighborhood of the shul gave me an open invitation to eat by them when it was raining, so that I shouldn’t have to walk back home in the rain. And yes, they had teenage daughters (one of whom was my sister’s best friend).
I’m sure that there are those on these boards who will say that this kind family was participating in the worst kind of aveira by having a single guy over while their single daughters were there. Suffice it to say that I disagree with them.
