Admittedly, my FH is absent-minded and often loses his headphones. But I know he has them today b/c we talked this morning with him using them! (I often ask b/c he likes the "togetherness" of phone calls on speaker phone while his son is in the car, and I find it intrusive). We are apart this week b/c of my work, and he was calling me on his way home from a work function that he took his 10 year old son to (b/c it was moved to Monday, I am not there to be with the son, and the BM wouldn't take him), and without me knowing it the whole, f-ing conversation was on speaker phone!!!
