Spoke Shave Plane

3 weeks ago i started talking to this kid from germany and we like realy conected so i sent him a plane ticket so he could come live with me and and hes been here with me for like 3 days. he brought his friend and his friend is like realy weird but he speaks english and german well so he can translate when we dont know what eachother is saying. uh so i brought Lowell (the guy im dating) to the gorcery store to get food he likes and he picked out a bunch of food but he wont eat at dinner time he likes to eat in the closet.last night while we were having sex i caught his friend watching while touching himself. Also last night i woke up and Lowell was trying to shave my cats back.

so my questions are is it normal in germany or europe to eat in closets and shave cats?
and how can i tell lowell that his friend is a creep and needs to leave.
