Update - Sticky Fingers
When I got home last night I decided to put the flash drive back in SS13's bedroom (where I found it). Just wanted to see how this would play out. I figured depending on how SS13 responded I could always confront SS13 about it.
I brought up the flash drive at dinner. It was just DH, SS13 and me, SS18 was out with friends so he missed dinner.
I casually asked, "Has anyone seen my flash drive? The last time I saw it it was with my Surface Pro."
DH: "No, but is it on the top of the entertainment center."
ME: "I checked, it's not there."
SS13: "Is it black and red?" *trying to act matter-of-factly, and looking down at his plate.*
SS13: "I think it maybe in either my room or SS18's room. I'll check after dinner."
DH: "Why would it be in your bedroom?"
SS13: "I don't know that's just where I remembered seeing it."
ME: "How did it get there?"
SS13: "I have no idea. I just remember seeing it there."
DH: "OK." *giving me the BettyRay-drop-it-look*
After dinner SS13 went to take a shower.
I told DH: "doesn't it seem odd that SS13 would say it may be in their bedrooms?" DH looked at me with a weird expression and said "yes". I dropped it and started clearing the table and doing dishes.
DH left the table and started looking for the flash drive, moving the TV and looking in the entertainment center. When he didn't find it there DH started looking around SS18's room for it. DH said to me: "What if SS18 just took it?" I said I don't know but did you check SS13's room? DH said no and that he wanted SS13 to check his own room. I said fine and went back to what I was doing.
When SS13 got out of the shower DH told him to look for the flash drive in his room. SS13 came out of his room a couple of seconds later and said it wasn't in there. DH dropped it by saying, "it will turn up".
I checked SS13's room and noticed the flash drive was still under his bed. I decided to leave it there and see if he would take it with him when he left this morning. I took a picture of it with my cell.
It was still there after SS13 left for summer school this morning. The boys are with BM tonight but will be back tomorrow. I decided I'll "find it" tonight. When I put the everybody's laundry away tonight.
I find it amazing how blind DH is when it comes to SS13. I took all the restraint I had not to keep questioning SS13 about the flash drive when he volunteered that it could be in their bedrooms. That was a huge red flag and DH just let it go. :?
