I opened the door to see the mailman standing there. After exchanging a brief word of greeting, he handed me a letter. I looked at the front to find it held my name. I bid him farewell and shut the door, before making my way to the kitchen. Once there, I grabbed a knife to open the envelope, curious and anxious to see what news it held.
keep in mind, there are more than the 3 basic tenses (past, present, future), and they can be mixed to an extent. If you include minor nods and adjustments as well, it can fill out the scene without seeming bulky. such as when I said "After exchanging a brief word of greeting", i set up an order of action (saying "Hi" was first, whatever was said next came 2nd), and it fills out a minor detail without adding bulk.
