He thinks it's funny

My husband thinks it's really funny that there are some things that he does all the time that when I try and do, don't do it very well.  For instance, I can never remember how to get our camera ready to upload pictures to my computer.  I can figure it out eventually but since my husband does it 90% of the time, it always takes me longer.  Just recently I was trying to find where the SD card was in our cameras while my husband watched and chuckled. I felt pretty silly but seriously, I rarely do it often!  If I did, I wouldn't have to think twice about it. :P  My computer has been slowing down recently and I don't know why or how to fix it.  My husband said he could work on it though so hopefully that helps because I don't have any idea.  I don't know much about computer things, like seagull scientific products, but I know enough to work my computer lol.  That says something right? lol  At least my husband didn't laugh when I told him my computer needed attention. :)
