I can't laugh at this. It seems like subconsciously he wants more than a fling... Or maybe not.

Tell him that you wouldn’t have bothered letting him know he left his swim suit, underwear and icky shoes , since they were nasty anyway, but you noticed his Cuff links on your nightstand and since they look expensive, you figured he could grab his other crap as well, but then, say Oops, sorry ... the cuff links weren’t his!

Listen to your friend. ☺

Either the goodwill or burn it.

Drop them at the good will store.

He should be able to leave exactly 43 articles of clothing at her place before she should expect an obligatory call but then only of 14 minuets in duration...it is right there in the damn contract, if you would only read it.

I don't need the underwear and swimsuit, but I do need my shoes back. Sorry I didn't call. I, um, lost your number. Yeah. That's it.

I am size 12 but not my type of shoes. I got like 10 swimming trunks with me in Maryland, Retired, they are obligatory. The woman once became my wife, broke with me as a GF and left some nice expensive shoes, First visitor to my place that fitted them, walk out with them. She came for them 30 days later. I simply said.... "you were not here and looked good on her. I never expected to see you again." She still married me. Me giving her the house on the divorce made up for the shoes I reckon. Your friend has work to do.

Maybe he expects you to clean his clothes?

Those clothing items look like a Fuck Boy Starter Kit. Burn the rags and bury them where no one can purchase them again

Last Friday and this Monday? Yeah if ya don’t hear from him by tomorrow tryin to make plans for the weekend I’d prob toss his stuff.

Money is all I can think of?
