Wednesday night I was at the grocery store and passed by this cute guy a few times on accident trying to find certain items. We made eye contact and thought nothing of it. Then I was at my car and packing my groceries in and he comes up all out of breath and says "I wanted to catch you before you left... (introduces himself) Can I have your number?" We talked a bit, he texts me later that night, but the convo dies pretty fast. We texted shortly yesterday and the implication to hang out was present, but he never actually asked, but seemed interested. Would I seem "thirsty" (not sure any other way to put it) if I were to ask him to hang out? Also, should I text him first?
