Told g/f i wanted to buy some inflatibles...and she laughed?

We went by a place with a large ghost and and giant pumpkin inflatible for halloween. And I said I wanted to get some inflatibles for my house and she laughed her head off...I asked why and she said "oh, no reason tee hee" Do you think its funny for a grown man to rock the inflatibles every so often? I think some people get great joy from them, I'm really "into" inflatibles, sure they just sit there and do nothing while you do all the work, but their cool...right?
