The number of suitcases

Sometimes I wonder how many suitcases it's normal to have. We have several shelves in the garage filled with suitcases and bags in all sizes.

Is this a side effect of being an Alien or is it just a suitcase addiction?

(oh, I know my husband would claim it's my addiction... but then he seems happy enough when he always can travel with the perfect sized suitcase or bag)

And we use them all. Not at the same time, but a combination of a few of them every time we travel.

Usually the bags are half empty when going east and overloaded when going west.
