Mine would like me to think he gets mad...but I do buy more when he's with me because I buy what HE likes in addition to what I like! My usual trips are $30-50. Last time he was with me, it was $175! I had him assemble the kit he wanted me to buy. He did pretty good! (I just need to mess with the borders to make it bigger.)
I only show off what I buy at the LQS when he know's I'm going there. I do make a few lunchtime trips per month. He doesn't need to know everything!
He always gives me the evil eye when the UPS truck comes anywhere near the house...LOL But I've been very good since Christmas!
