I was sitting in a coffee shop with my husband and a new friend (of mine... old friend of his) and I looked at the sleeve of my jacket-thing (it has long sleeves, but is short and ends at about where an empire waistline is). There's a hole in the seam, so that it looks like one sleeve has a thumb-hole, where my thumb is supposed to go. Except, I'm always leery about using it as such because I don't want to make the hole worse. And I'm always meaning to sew it up and make it... better. But I had rifled through my purse and found my sewing kit for a reason that currently escapes me... so I decided to fix up my sleeve. It was the most random thing, but there I was in the middle of a coffee shop, sewing on the jacket I was wearing... I'm amazed I didn't stab myself. The other thing I've been intending to do to that jacket is rip the seam on the other side and make a matching hole... I didn't do that last night because a)due to my recent airport visits, I don't have a pocketknife on my keychain anymore... nothing to cut with b)it would have meant sewing on my right sleeve, and I'm right-handed.
It was pretty funny when my new friend finally acknowledged what I was doing verbally. Suddenly she's all, "So... you're sewing your jacket." It was pretty random, I admit. I think it's a good thing, though, to do upon a first acquaintance; it gets her used to my personality. It's a fairly typical thing for me to do, don't you think?
