One time I was out in the yard talking to a neighbor who had a collection of live pet birds, and she started going on and on about how she had to drive an hour to get bird food in bulk because the local stores were too pricey. About that time, one of my cats wandered over and started rubbing against my foot, and the neighbor kept droning on and on about the cost of bird food. I finally said something like" I don't think bird seed is that expensive, I just buy a big bag and spread it around in the backyard. Its cheaper than cat food" I thought this was pretty funny. That lady never talked to me again. Ever.
Another time I was in a convenience store getting coffee,and a lady working there was checking the various coffee urns, and she said hi, how ya doing, I said fine, how about you, and she said "I'm really good" and before I could stop myself, I heard myself say "That's what I hear" Luckily for me it was only a split second of being really embarrassed before she burst into laughter, and said I made her day.
So, humor can be a tricky thing.
Anyway, I figure it has to be worn door checks. There was a thread recently where vferdman overhauled the door checks in his 06 Matrix, a bunch of pics if you want to see what the part looks like.
I'd bet money the same part number door checks in your '10 vibe are used in other vehicles as well, but I can't say for sure which though. Depending on where you buy them, they can be pricey, so if you think it might be the door checks, maybe get just the front driver door one and see if that helps before you spring for new checks for the other doors
