My friends and I were having a barbeque a few weeks ago and this guy that I like was there. We hang out every once in a while and it seems like we have really good chemistry and after meeting him a few times he told me that he thought I was "nice and beautiful". He is always poking and grabbing my sides and joking around with me and will put his arm around my shoulders. We had all just got done eating and he came up to me and was joking and I was squirming and he picked me up completely in the air where my waist was at his shoulders just to pick on me. Why do you think he did this? Is he just friendly or flirty or possibly interested?
