Here we go again. The MR started over the weekend, and as i mentioned (repeatedly) in March, all kinds of frustrations are likely to occur for three weeks, involving travel, communications, electronics, buying/selling, learning/teaching.... So hold on to your hats ... er, patience!
The secret to "surviving" a MR is to check and double-check EVERYTHING. Leave early, mail it registered, take an extra battery for your cellphone -- you get it.
On the other hand, retrogrades are good for some things. Old projects which are unfinished may get a new lease on life. You may run into old friends, or regenerate a relationship which you thought was over. Watching old movies and listening to old music will be particularly appealing, and nostalgia will be in the air.
Me, i'm going to be working on the renovations of my living room, which have been in process for YEARS. I have every confidence that it will work out well.
