We were bad witnesses. We bought lots of stuff for our kids, although I think we part of a fairly "liberal" congregation. We always made a big deal of exchanging presents on our anniversary. As soon as they got old enough to figure out when it was coming up the children started getting excited, much like Christmas. It was a fun family tradition. And we always hit the after Christmas sales so that when school started up again so that our kids could say that got something new and leave it at that.
If we'd lived somewhere else I wonder if we would have been disfellowshipped for giving our son Star Wars minitures and our daughter Strawberry Shortcake stuff.
Stand for Pure Worship, JW's aren't the only ones who give oddball high school graduation presents. The other day I read something from a college student talking about his graduation gifts. One of the comments was "What am I supposed to do with a Cross pen desk set?"
