It was definitely hard to disappear for an hour meeting to a place that's a half hour from my house. I'm concerned about how I will pull that off regularly, although some plans are forming in my mind.
Hi, speaking from experience, do not lie about where you are going. Don't make up stories to make it something that it's not.
One of the fundamental parts of SA is being honest, making things up will not only negatively effect your program, but people around you will notice that something is up (I used to tell people that I was going to a chavrusa, it worked for a bit, until people started asking for details. It's very hard to keep fake details straight in your head... A person's wife might notice these mistakes and start suspecting something, and/or feel like there is something wrong, that their husband doesn't trust them ect.)
A few suggestions that have worked for me:
1) I tell people that I have somewhere to go, and leave it at that. I don't tell them what or where, and if they push I brush it off or just tell them that I would appreciate them respecting my privacy (I don't know it this is recommended for someone's spouse... I'm not married, so never had to try)
2) I am going to a private self help workshop/shiur
3) I am going to an appointment/meeting/shiur (if they ask what it's about, see #1 above)
These are just a few suggestions that might help, but ask around and find out what works for other people.
And above all, don't make things up.
Wishing you much Hatzlacha.
All the best,
