I adore my friends and love being with them, but after 3 hours I'm wiped out. One of my petty peeves is that friends don't seem to understand that after 3 hours I'm tired out. Plus my dog has renal disease and it stresses her. I invited two friends over for lunch and a short activity....thinking four hours would be plenty. Five hours into it and I had to drop subtle hints that it was time for them to go. I hate that. In the past I would tell them we would get together from [e.g.] 12-3.....and sometimes that would work. How do YOU get people to leave. I suspect the answer is to stop inviting them to my home.
